ABSTRACT
We investigate the young stellar objects (YSOs) in the Lynds 1641 (L1641) cloud using multi-
wavelength data including Spitzer, WISE, 2MASS, and XMM covering ∼1390 YSOs across a range
of evolutionary stages. In addition, we targeted a sub-sample of YSOs for optical spectroscopy. We
use this data, along with archival photometric data, to derive spectral types, extinction values, masses,
ages, as well as accretion rates. We obtain a disk fraction of ∼50% in L1641. The disk frequency is
almost constant as a function of stellar mass with a slight peak at log(M∗/M⊙)≈−0.25. The analysis
of multi-epoch spectroscopic data indicates that the accretion variability of YSOs cannot explain the
two orders of magnitude of scatter for YSOs with similar masses. Forty-six new transition disk (TD)
objects are confirmed in this work, and we find that the fraction of accreting TDs is lower than for
optically thick disks ( 40–45% vs. 77–79% respectively). We confirm our previous result that the
accreting TDs have a similar median accretion rate to normal optically thick disks. We confirm that
two star formation modes (isolated vs. clustered) exist in L1641. We find that the diskless YSOs
are statistically older than the YSOs with optically-thick disks and the transition disk objects have
a median age which is intermediate between the two populations. We tentatively study the star
formation history in L1641 based on the age distribution and find that star formation started to be
active 2–3 Myr ago.

1. INTRODUCTION
Circumstellar disks, as a byproduct of the star-
formation process via angular momentum conservation,
play a key role in the formation of new stars, and sub-
sequent planetary systems. The investigation of the disk
evolution is thus important to understand both star for-
mation and planet formation.
The disk dissipation processes have been constrained
by surveys of large samples of young stars. These surveys
probe the inner disk regions using excess emission above
the stellar photosphere at infrared wavelengths and find
that the lifetime is several Myrs (Strom et al. 1989b;
Haisch et al. 2001; Hillenbrand 2002; Hern´andez et al.
2007a; Sicilia-Aguilar et al. 2006b; Fang et al. 2013).
The large variety of disk morphologies observed at a
given age suggests that the disk evolution is controlled
by several parameters: stellar and disk mass, multi-
plicity, local environments, etc. (Hartmann et al. 2006;
Bouwman et al. 2006; Guarcello et al. 2007; Fang et al.
2009, 2012).
Observations at infrared wavelengths suggest that
there are two types of evolved disks: radially depleted

disks and globally depleted disks. The radially de-
pleted disks show very weak or no infrared excess at
near infrared wavelengths, but strong excess emission at
mid-infrared and longer wavelengths, suggesting dust in
these disks are cleared starting from the inside and mov-
ing outward (Hayashi et al. 1985; Osterloh & Beckwith
1995; Meyer & Beckwith 2000; Mamajek et al. 2004;
Andrews & Williams 2005; Carpenter et al. 2005). The
globally depleted disks exhibit an approximately uni-
formly reduced infrared excess compared to primordial
disks over all wavelengths out to 24 µm (Lada et al. 2006;
Sicilia-Aguilar et al. 2008, 2009; Currie & Kenyon 2009;
Currie et al. 2009; Currie 2010), indicating there is global
dust depletion in these disks. The investigation of the
two types of evolved disks are important to understand
the disk dissipation processes.
The radially depleted disks, usually named TDs,
are better studied in the literature than the globally
depleted disks. In the following, without specifica-
tion we only refer to the radially depleted disks as
TDs. There are several processes proposed to produce
TDs, including (1) giant planet formation (Rice et al.
2003; Quillen et al. 2004), (2) tidal truncation in
close binaries, (3) photo-evaporation (Johnstone et al.
1998; St¨orzer & Hollenbach 1999; Richling & Yorke
2000; Hollenbach et al. 2000; Clarke et al. 2001;
Armitage et al. 2003; Alexander et al. 2006), (4)
magnetorotational instability (Chiang & Murray-Clay
2007), and (5) dust grain growth (Sicilia-Aguilar et al.
2011). To distinguish these mechanisms, an important
diagnostic is the comparison of the accretion rate of mat-
ter onto the central star between transition disk objects
and less evolved classical T Tauri stars (Najita et al.
2
2007; Sicilia-Aguilar et al. 2010; Cieza et al. 2010).
For the normal classical T Tauri stars (CTTS),
various studies have suggested that there is an em-
pirical correlation between the average accretion rate
and the mass of the central star of ˙
Macc ∝Mα
∗, with
α≈1-3 (White & Basri 2003; Muzerolle et al. 2003;
Calvet et al. 2004; Muzerolle et al. 2005; Mohanty et al.
2005; Natta et al. 2006; Garcia Lopez et al. 2006;
Herczeg & Hillenbrand 2008; Gatti et al. 2008;
Fang et al. 2009). Although the correlation be-
tween accretion rate and stellar mass is obvious for a
large sample of young stars, individual objects with
similar ages and masses commonly scatter around
the average relation by up to 2 orders of magnitude.
Multiple epoch observations of the same stars can show
large variations in the Hαemission strength and line
profile, pointing at substantial temporal variations in
the accretion (Johns & Basri 1995; Gullbring et al.
1996; Alencar et al. 2001; Alencar & Batalha 2002;
Sicilia-Aguilar et al. 2010), which provides one plausible
potential explanation for the large scatter in the ˙
Macc vs.
M∗relation. Other explanations for such a large scatter
relate to initial conditions, angular momentum, disk
mass, and substantial time evolution (Hartmann et al.
1998; Dullemond et al. 2006).
To address all of these questions, we need to study a
large sample of well characterized young stars. L1641 is
one of the best sites for this investigation. L1641 is lo-
cated in the Orion molecular cloud complex at a distance
of 400-500 pc (e.g. Anthony-Twarog 1982; Hir ota et al.
2007), and the region probably has a “depth” of at least
several tens of parsecs. In this work, we will assume a dis-
tance of 450 p c. In L1641, a large p opulation of young
stars are formed in relative isolation, in addition to a
population of young stars in many clusters or aggregates
(Strom et al. 1993; Allen 1995; Fang et al. 2009). The
Spitzer observations of this region have yielded excellent
samples of thousands of young stars down to very low
mass including both substantial numbers of TDs as well
as normal T Tauri stars (Fang et al. 2009; Megeath et al.
2012). In Fang et al. (2009) (hereafter Paper I), we per-
formed a large spectroscopic survey of YSOs in L1641
with VLT/VIMOS. Using these data, in combination
with the optical and near-infrared photometry, we de-
rived the masses, ages, and accretion properties of a sub-
sample of YSOs in L1641, and related these properties to
their disk properties traced by the Spitzer observations.
Following the work in Paper I, we perform a new optical
spectroscopic survey of young stars in the L1641 cloud
with the MMT/Hectospec and the MMT/Hectochelle.
In this work, we report on the results from these obser-
vations. The data from Hectospec can cover a wave-
length range from 3700–9000˚
A, and are used to con-
firm the youth and determine the spectral types of YSO
candidates in L1641, especially for the TD candidates
proposed in Paper I. Furthermore, the spectra from Hec-
tochelle can cover the Hαline with high spectral resolu-
tion. In this work, a group of YSOs in L1641 have been
observed at multiple epochs with Hectochelle, aimed at
monitoring the accretion variations of YSOs in L1641.
We arrange the paper as follows: in §2 we describe our
observations and data reduction, in §3 we delineate our
data analysis, we present our results in §4, followed by a
Figure 1. r′vs. r′−i′color-magnitude diagram. The grey filled
circles show all the sources found in the L1641 field (Paper I), the
open circles and diamonds are the targets for the spectroscopic
survey with Hectospec and Hectochelle, respectively. The pluses
mark the YSOs in Paper I. The solid line shows the 10 Myr pre-
main-sequence (PMS) isochrone from Dotter et al. (2008)
discussion in §5, and we summarize our efforts in §6.
2. OBSERVATIONS AND DATA REDUCTION
We combine spectroscopic data newly obtained
with Hectospec (Fabricant et al. 2005) and Hectochelle
(Szentgyorgyi et al. 2011) with photometric data from
Paper I. We use the spectr oscopic data to do the spectral
classification, and characterize the accretion properties
of YSOs in L1641.
2.1. Photometry
Our photometric data used in this work are mainly
extracted from Paper I (see the description in Paper I).
We complement them with the data from the UKIRT
infrared deep sky survey (UKIDSS, Lawrence et al.
2007), and Wide-field Infrared Survey Explorer (WISE,
Wright et al. 2010). We briefly describe each dataset as
follows.
Our optical photometry are partially taken from the
Sloan Digital Sky Survey (SDSS, York et al. 2000) in the
u′g′r′i′z′bands centered on 0.35, 0.48, 0.62, 0.76 and
0.91 µm, respectively. The 10σlimiting magnitudes for
the SDSS survey of the L1641 cloud are ∼20.5, 21.7,
21.4, 21.1 and 19.7 in the u′g′r′i′z′bands, respectively.
The SDSS survey has not covered the south-east half
of the L1641 cloud, toward which we complemented the
SDSS photometry of L1641 with CCD imaging in the
SDSS g′r′i′z′bands performed at the Calar Alto 3.5m
telescope, using the Large Area Imager for Calar Alto
(LAICA). Conditions were photometric, but the seeing
was poor (2–3′′ ), somewhat limiting the sensitivity for
faint point sources (∼19.6, 19.6, 19.9, and 18.9 mag at
g′r′i′z′bands, respectively).
The near-infrared photometry in the JHKSbands was
taken from the Two-Micron All Sky Survey (2MASS,
Skrutskie et al. 2006), with 10σlimiting magnitudes of
∼16.2, 15.3, and 14.6 mag, respectively. The north-
west part of the L1641 cloud (DEC (J2000)>−6.44) has
YSOs in L1641: Disks, Accretion, and SFH. 3
been observed by the UKIRT infrared deep sky survey
(UKIDSS, Lawrence et al. 2007), in J HK bands, with
10σlimiting magnitudes of ∼19.3, 18.2, and 17.6 mag,
respectively. For a few objects which are too faint to be
detected in the 2MASS survey, we extract their photom-
etry in the UKIDSS catalog.
The mid-infrared photometry for the sources in the
L1641 cloud are extracted from the Spitzer IRAC and
MIPS imaging data (see the detail description for the
data reduction in Paper I). The 10σlimiting magnitudes
for the IRAC and MIPS imaging survey of the L1641
cloud are ∼17.5, 17.2, 14.4, 12.2, and 9.0 mag in the
IRAC [3.6], [4.5], [5.8], [8.0], and [24] bands, respectively.
The L1641 cloud has been covered by the WISE survey
at wavelengths of 3.4, 4.6, 12, and 22 µm with spatial
resolutions of 6.
′′1, 6.
′′4, 6.
′′5, and 12.
′′0. We also extracted
the mid-infrared photometry from the WISE survey. The
10σlimiting magnitudes are estimated to be ∼16.4, 15.1,
10.7, and 7.1 mag in the WISE [3.4], [4.6], [12], and [22]
bands, respectively.
2.2. X-ray emission
Young stars can be identified by their X-ray emission,
which is 2 to 3 orders of magnitude brighter than seen
in the field population (Feigelson & Montmerle 1999).
Thus, complementary X-ray data can be extremely useful
to distinguish young stars from field stars in star form-
ing regions. The L1641 cloud has been almost fully cov-
ered by the XMM survey (Wolk 2009). The sky coverage
of the XMM survey is shown in Fig. 2. All the X-ray
emission sources detected in the survey have been pub-
lished in the XMM-Newton Serendipitous Source Cat-
alogue (Watson et al. 2009). We have extracted ∼940
X-ray sources from the XMM Serendipitous Source Cat-
alogue in the field of L1641. We matched the X-ray
sources to our targets using 2′′ tolerance, and found op-
tical and/or infrared counterparts for 66% of the X-ray
sources. We consider these X-ray emission sources to be
likely YSO candidates. We must stress that a small frac-
tion of “YSOs” in our catalog can be bright AGN and
nearby foreground stars. Without spectroscopic data,
these sources are difficult to be excluded.
2.3. Optical spectroscopy
2.3.1. Target selection
We select the targets for our spectroscopic observations
if they obey any of the following criteria:
1. X-ray emission
2. Infrared excess
3. Above the 10 Myr PMS iso chrone
To reach enough SNR for spectral classification, we se-
lect the sources with SDSS r′magnitude brighter than
than ∼19 mag. One additional target, fainter than
19 mag in at r′band but very bright at i′band, is also in-
cluded in our spectroscopic sample with Hectospec. For
the spectroscopic survey with Hectochelle, we select the
YSOs with SDSS r′∼12–19 mag. Figure 1 shows the r′
vs. r′−i′color-magnitude diagram of our targets for
both spectroscopic surveys.

exposures
2.3.2. Spectroscopic observations and data reduction
The intermediate resolution spectra of sources are
taken with the Hectospec multi-object spectrograph
which can take a maximum of 300 spectra simultane-
ously. We used the 270 groove mm−1grating and ob-
tained spectra in the rang e 3700–9 000 ˚
A with a resolution
of ∼5˚
A. We have ∼450 targets, which are distributed at
3 pointings (see Fig. 2). The observational data were
taken at the nights on 2011 Jan 23, 24, and 25. Table 1
lists the observational logs.
The high-resolution Hαspectroscopy of sources are ob-
tained with the Hectochelle multi-object spectrograph
which can take a maximum of 240 spectra simultane-
ously with a spectral resolution of 34000. We used the
OB 26 filter which simultaneously cover Hαemission line
and Li I λ670 8 ˚
A absorption line. The observational data
were taken at the night on 2010 Feb 5 with two pointings.
On the nights on 2010 Mar 3, 2010 Nov 29, and 2011 Oct
19, a major fraction of our targets were observed again.
The observational logs are listed in table 1.
Toward each pointing observed with Hectochelle or
Hectospec, we have taken at least one extra set of sky
spectra by offsetting the telescope by ∼5–10 arcsec be-
tween the science exposures, which can provide us with
a sky spectrum close to each object. Together with the
rest of sky fibers at each science exposure, this enables us
to construct the appropriate nebular and sky spectrum
for subtraction, taking into account the different trans-
mission of every fiber and the variability of the nebular
and sky emission throughout the field of view.
We use the IRAF routines to reduce the Hectospec and
Hectochelle data according to a standard procedure. We
flat and extract the spectra using dome flats with the
IRAF task dofibers under the package specred. The
wavelength solution is achieved with HeNeAr and ThAr
comparison spectra for Hectospec and Hectochelle, re-
spectively, using the IRAF task identify and reidentify
under the package specred. We calibrate the spectra
with a wavelength solution constructed using the IRAF
task dispcor under the package specred. For each point-
ing, we have done the observations at several exposures.
We extract the spectra for each exposure. Finally, we
obtain the spectra for each target and the correspond-
ing sky spectra close to this target. We subtract the sky
from the spectra of each target, and combine the sky-
4
subtracted spectra into one final spectrum.
2.3.3. Complementary literature spectroscopy
An additional sample of 12 stars with spectral types,
of which 10 are from Allen (1995) and 2 from our VI-
MOS spectroscopic survey, are also included in this work.
These stars show X-r ay emission, but are not in Paper I.
Thus, we include them in this work.
3. ANALYSIS
3.1. YSO selection criteria
A star in our sample is classified as a young star if it
obeys any of the following criteria:
1. X-ray emission
2. Infrared excess
3. Hαemission
When good SNR Hectochelle spectra are available, we
also use the Li I λ6708 ˚
A absorption line as an indicator of
youth. We find that sources with strong infrared excess
emission always show Hαemission, but do not always
show X-ray emission. We also find that some stars with
X-ray emission show Hαabsorption. These stars typi-
cally have spectral types from late A to late G. We note
that there may be a small contamination of our sample
from dMe stars, which are old, M-type stars that show
Hαemission due to chromospheric activity, and from ex-
tragalactic sources which show infrared excesses and/or
X-ray emission.
3.2. Spectral classification
We classified the Hectospec spectra using the scheme
developed by Hern´andez et al. (2004), which employs the
empirical relation between the equivalent widths of se-
lected atomic and molecular absorption lines and the ef-
fective temperature. The classification scheme consists of
of 3 subregimes, each combines a number of absorption
features and spans a range in spectral types (See the
detailed description of the method in Hern´andez et al.
2004).
In Fig. 3, we show sample Hectospec spectra of stars
with spectral types from late-G to late-M from our sur-
vey. There is a clear change in the spectral shape with
spectral type, especially the TiO strength, which is a
prominent diagnostic for late K to M type stars.
Of the ∼430 targets with spectral-type estimates in our
spectroscopic sample, ∼290 sources have been classified
in the litera ture (Paper I; Allen 1995; Gˆalfalk & Olofsson
2008; Hsu et al. 2012). Figure 4 shows the comparison
of the spectral types in this work and those quoted in
the literature. About 90% of this sample agrees within
1 subclass, 95% within 2 subclasses.
3.3. Determining the stellar properties
We converted the spectral types to effective tem-
peratures using the relation from Kenyon & Hartmann
(1995) for stars earlier than M0, and the one from
Luhman et al. (2003) for stars later than M0. We deter-
mined the extinction and bolometric luminosity of the
central stars in the YSOs by fitting their optical and
near-infrared photometry with a (reddened) model atmo-
sphere with the effective temperature derived from spec-
tral classification. We adopted models by Kurucz (1979,
1994) at temperatures ab ove 4500 K, and the MARCS
models at lower temperatures (Gustafsson et al. 2008).
The fitting employs two free parameters: the angular
diameter (θ) and the extinction (AV) in Vband. In gen-
eral, we use the photometry in g′,r′,i′,z′from SDSS,
and in Jbands for our SED fit, but for stars without
near-infrared excess emission we also included the Hand
Ksbands. We calculated the synthetic photometry by
integrating the intensity of the (reddened) model atmo-
spheres over the spectral response curve of the system
for each filter, and compared them with the observations.
By minimizing the χ2in an automated iterative proce-
dure, we obtained the optimum values for θand AV. We
used the extinction law of Cardelli et al. (1989) to red-
den model atmospheres, and adopted a total to selective
extinction value typical of ISM dust (RV=3.1).
We calculated the bolometric luminosity of stars
from the effective temperatures and angular diam-
eters assuming a distance of 450 pc (Genzel et al.
1981; Anthony-Twarog 1982; Maddalena et al. 1986;
Wilson et al. 2005), using the following formulae:
Lbol =πθ2d2σT 4
eff (1)
where θis the angular diameter, dis the distance, σis
the Stefan-Boltzmann constant, and Teff is the effective
temperature.
With effective temperatures and bolometric luminosi-
ties, we can place the YSOs in the HR diagram from
which stellar masses and ages can be estimated by com-
parison to theoretical pre-main sequence (PMS) evolu-
tionary tracks. However, several sets of such tracks ex-
ist, by various authors, which yield significantly different
results on stellar ages (see e.g. Hillenbrand et al. 2008,
for a discussion). We estimated masses and ages us-
ing five different sets of publicly available PMS evolu-
tionary tracks by D’Antona & Mazzitelli (1997) (DM97),
Baraffe et al. (1998) (B98), Siess et al. (2000) (S00),
Dotter et al. (2008) (D08), and Tognelli et al. (2011)
(Pisa11). In the remainder of the discussion, if not specif-
ically mentioned, we will adopt the values obtained from
the tracks of Dotter et al. (2008), as these have the best
resolution in both mass and age. We stress, however,
that there are substantial systematic differences between
the different sets of tracks (see Hillenbrand & White
2004; Hillenbrand et al. 2008, for a detailed discussion
of the various sets of PMS evolutionary tracks available
in the literature), and our motives for choosing those by
Dotter et al. (2008) are pragmatic.
We employ the same metho d as in Paper I to estimate
the uncertainties in mass and age of the individual stars.
We use a simple Monte-Carlo method to created a large
number of synthetic [Teff ,L∗] points for each star, as-
suming the errors in both quantities to be normally dis-
tributed. For each point in the HR diagram, we derived
the mass and age, and use the standard deviations in the
resulting mass and age distribution as their uncertain-
ties. This procedure can account for the observational
errors, but the systematic uncertainties from different
PMS evolution tracks remain. In addition, for highly ex-
tincted sources, the shape of the adopted extinction law

can affect the resulting mass and age by affecting the
stellar luminosity estimate. Higher values for the total
to selective extinction RVcan lead to higher stellar lumi-
nosities, which yield younger ages for YSOs, and higher
masses for YSOs with the earlier spectral types.
3.4. Determining the disk properties
3.4.1. Infrared spectral slopes and Classifications
We calculate the infrared spectral slope for each YSO,
defined as α=dlog(λFλ)/dlog(λ), with the dereddened
photometry in the infrared broad bands. We calculate
four sets of infrared slopes, α2−8,α3.6−8,α2−24, and
α3.6−24, corresponding to the spectral range of Ksto
[8.0], [3.6] to [8.0], Ksto [24], and [3.6] to [24], respec-

into three regions marked as numbers 1, 2, and 3, in the figure. In
each region, we use different ways to estimate the extinction of the

tively. The extinction of each YSO is estimated individ-
ually. For the YSOs with spectral-type measurements,
we can accurately estimate their extinction by fitting
their optical and near-infrared photometry as described
in Sect. 3.3. However, for the YSOs without spectral
types, we can only roughly determine their extinction
with a method similar to that used by Gutermuth et al.
(2008) in which the extinction is obtained employing the
H−Ksvs. J−Hcolor-color diagram. We describe the
method as follows.
The location of each YSO in the H−Ksvs. J−Hcolor-
color diagram depends on both its intrinsic colors and
its extinction. To estimate the extinction of individual
YSOs, we need to have knowledge of their intrinsic colors.
For the diskless YSOs, their intrinsic colors are mainly
determined by their spectral types. For YSOs with disks,
the excess emissions from hot inner regions of disks can
also contribute to their intrinsic colors and make them
redder than diskless stars. The CTTS locus in the H−Ks
vs. J−Hcolor-color diagram is observationally defined
as the colors of dereddened classical T Tauri stars. In
consideration of these different origins of intrinsic colors
of YSOs, we divide the diagram into 3 sub-regions (see
Fig. 5). Within each region, we use a different way to
obtain the intrinsic color [J−H]0of the sources. Extinc-
tion values of individual YSOs are estimated from their
observed [J−H] ([J−H]obs) and [J−H]0using the equa-
tion: AK=([J−H]obs−[J−H]0)/0.95. In Region 1, the
sources show slightly bluer [J−H] colors than expected
from normal reddening of diskless YSOs, probably due
to the photometric uncertainties. For such YSOs, their
[J−H]0values are simply assumed to be 0.6 (the typ-
ical value for a K5-type dwarf star). In Region 2, the
color excess of each source is mainly due to reddening.
Its intrinsic [J−H] color is obtained from the intersec-
tion between the reddening vector and the locus of main-
sequence stars6. In Region 3, the sources are supposed
6For simplicity, we force [J−H]0≥0.6 as done in
Gutermuth et al. (2008)
to be the reddened classical T Tauri stars. The intrinsic
[J−H] color is derived from where the reddening vector
and the CTTS locus intersects. For the stars outside of
these three regions, or without detection in all the three
2MASS bands, their extinction is assumed to be zero.
The extinction values derived from the H−Ksvs. J−H
color-color diagram are less accurate than those of YSOs
with spectral types. For a sample of spectroscopic YSOs
with substantial extinction (Av>1), we compare the ex-
tinctions estimated from the above rough method with
the more accurate ones described in Sect. 3.3. We find
the extinctions from the rough method are statistically
slightly lower than the relatively accurate ones. We es-
timate how the extinction affect the spectral slopes. For
AK=1, the dereddened α2−8,α3.6−8,α2−24, and α3.6−24
are 0.36, 0.14, 0.15, and 0.04 less than the observed spec-
tral slopes, respectively. Thus, given the typical extinc-
tion for our YSOs in L1641, extinction only slightly in-
fluences our estimates of the spectral slopes of the YSOs,
except for a few extremely embedded YSOs.
We classify the YSOs into different classes accord-
ing to the two spectral slopes, i.e. α3.6−8and
α3.6−24. For the sources with MIPS 24 µm de-
tection, we classify the sources as diskless stars if
α3.6−24≤−2.2, Class II sources if −2.2<α3.6−24<−0.3,
Flat-spectrum when −0.3≤α3.6−24≤+0.3, and Class I
source if α3.6−24 >+0.3 (Luhman et al. 2008). A part
of YSOs have not been detected at 24 µm. For
these YSOs, we use the dereddened infrared slope
(α3.6−8) to classify the young stars into Class III if
α3.6−8≤−2.56, Class II if −2.56<α3.6−8<−0.3, Flat-
spectrum when −0.3≤α3.6−8.0≤+0.3, and Class I sources
if α3.6−8.0>+0.3. For 857 YSOs with reliable estimates
of spectral types, their classes will be revised by compar-
ing their reddened model photospheric fluxes with their
observed fluxes at infrared wavelengths.
3.4.2. Accretion rates
Gas from the disk accretes onto the star along the
magnetic field lines and hits the stellar surface at ap-
8
proximately the free-fall velocity, causing a strong ac-
cretion shock and associated hot-spots on the stellar
surface. Various emission lines, such as the hydrogen
Balmer series, He I 5876 ˚
A, Brγ, etc., are formed in
the infalling magnetospheric flow (Hartmann et al. 1994;
Gullbring et al. 1998; Muzerolle et al. 2001; Lima et al.
2010; Kurosawa et al. 2011). Optical/ultraviolet ex-
cess continuum emission is produced in the accre-
tion shocks. All these emission lines or excess emis-
sion can be used to estimate the accretion rates
with the help of models or the empirical rela-
tion between line luminosity and accretion luminos-
ity (Paper I; Hartmann et al. 1994; Hartigan et al. 1995;
Gullbring et al. 1998; Muzerolle et al. 2001; Calvet et al.
2004; Natta et al. 2004; Herczeg & Hillenbrand 2008).
We use two methods to estimate the accretion rates:
(1) the empirical relation between accretion luminosity
and Hαor Hβlines luminosity from Paper I, (2) the em-
pirical relation between the full width of Hαat 10%
(F WHα,10% ) of the peak intensity and accretion rates
from Natta et al. (2004).
In the former method, we estimate the accretion rates
from the observed Hαand Hβline luminosity. The Hα
and Hβline luminosity are calculated by integrating over
the line profile, adopting the best fit model atmosphere
spectrum (see Sect. 3.3) as the continuum level. The line
luminosities are converted to the accretion luminosity via
the empirical relation g iven in Paper I:
log(Lacc /L⊙) = (2.27±0.23)+(1.25±0.07)×log(LHα/L⊙)
(2)
log(Lacc /L⊙) = (3.01±0.19)+(1.28±0.05)×log(LHβ/L⊙)
(3)
The inferred accretion luminosities are then converted
into mass accretion rates using the following relation:
˙
Macc =LaccR⋆
GM⋆(1 −R⋆
Rin ),(4)
where Rin denotes the truncation radius of the disk,
which is taken to b e 5 R⋆(Gullbring et al. 1998). G is
the gravitational constant, M⋆is the stellar mass as esti-
mated from the location of each star in the HR diagram,
and R⋆is the stellar radius derived using the fitting pro-
cedure described in Sect. 3.3.
For the YSOs with high-resolution Hαspectroscopy,
we distinguish accretors from non-accretors based on
the criterion (F WHα,10% >250 km s−1) described in Ap-
pendix A, and estimate the accretion rates with the em-
pirical relation between accretion rates and F WHα,10% ,
using the formula given by Natta et al. (2004):
Log ˙
Macc =−12.89(±0.3) + 9.7(±0.7) ×10−3F WH α,10%
(5)
A comparison of accretion rates derived from the above
two methods is discussed in Appendix B.
4. RESULTS
4.1. YSOs in L1641
In this section, we will perform a census of YSOs in
L1641 based on the data collected from several projects.
Then, we will calculate the infrared spectral slopes of
these YSOs, and classify them into different evolutionary
stages.
4.1.1. A census of YSOs
As one of the best studied star-forming regions in the
literature, L1641 has been observed by various projects,
including infrared imaging surveys (Strom et al. 1993;
Megeath et al. 2012), spectroscopic surveys (Paper I;
Allen 1995), and an X-ray emission survey (Wolk 2009;
Watson et al. 2009) (see FOVs of each survey in Fig. 2).
However, there has no been no available census of YSOs
in this region in the literature. In this work, we provide
an inventory of YSO candidates according to the follow-
ing selection criteria: (1) confirmed with spectroscopy in
Paper I and this work, (2) showing infrared excess emis-
sion, or (3) showing X-ray emission. A source is consid-
ered as a YSO if it obeys one of the above criteria. We
have identified 1247 YSOs.
Recently Hsu et al. (2012) presented a catalog of
∼860 young stars in L1641 confirmed with optical spec-
troscopy, among which ∼720 stars fall within the region
that we study in this paper. We compare our YSO sam-
ple with that of Hsu et al. (2012), and find ∼580 common
sources in both catalog. About 140 YSOs in the catalog
of Hsu et al. (2012) are absent in our census. Among
them, ∼120 sources are diskless stars, and ∼20 sources
are YSOs with the infrared excess emission. We did not
identify these diskless YSOs because they do not show
X-ray emissions and have not been observed with spec-
troscopy prior to the survey of Hsu et al. (2012). The 20
disked YSOs are located close to the edge of the cover-
age of the Spitzer survey, and lack photometry in several
IRAC bands in our previous photometric catalog. Here,
we include all these additional YSOs in our YSO catalog.
In table 2 and 3, we list the YSO criteria that they abide
by as well as their optical and infrared photometry.
In our YSO catalog, there are 1273 sources with pho-
tometry in all four IRAC bands. Figure 6(a) shows
their [3.6]−[4.5] vs. [5.8]−[8.0] color-color diagram. The
sources in the color-color diagram fall into two popu-
lations. A ma jor fraction of stars are located towards
the top-right of the origin due to infrared excess emis-
sion from hot dust in the inner disk, while other sources
reside in a cluster near the origin, consistent with photo-
spheric infrared colors. In Fig. 6(a), there are five sources
(ID#1074, 1218, 1220, 1233, and 1244) showing IRAC
colors distinct from the others. Those sources will be
discussed in Sect. 4.5.1.
Figure 6(b) shows the Ks−[5.8] vs. [8.0]−[24] color-
color diagram. Due to the lower sensitivity of MIPS,
only a few diskless stars are detected at 24 µm, and
appear around the origin in Fig. 6(b). A major frac-
tion of YSOs detected at 24 µm are harboring optically-
thick inner disks and are located within Ks−[5.8]>1,
and [8.0]−[24]>2. There is a minor group of YSOs with
Ks−[5.8].1, and [8.0]−[24]&2.5, indicating these sources
show very weak or no excess emission at the shorter
IRAC bands, but strong excess emission at 24 µm, char-
acteristic of TDs (see Paper I). The five unusual sources
in Fig. 6(a) are also marked Fig. 6(b). Among them, two
sources (ID#1074 and 1233) are not detected in both
the 2MASS survey and the UKIDSS survey, and an up-
per Ks-band limiting magnitude of 15.3 is assumed for
them. The source ID#1074 is not detected at 24 µm,
YSOs in L1641: Disks, Accretion, and SFH. 9
and its upper limiting magnitude at 24 µm is used for
the plot.
4.1.2. The completeness and contamination of YSO census
The datasets used in our YSO census consist of differ-
ent surveys, each of which has slightly different sky cover-
age (see Fig. 2), and different sensitivities to detect the
YSOs. The XMM survey is more sensitive to Class III
sources than Class II sources (Feigelson & Montmerle
1999), and insensitive to the intermediate mass stars
(Feigelson et al. 2003). The Spitzer imaging survey can
be used to identify YSOs with circumstellar disks. The
spectroscopic surveys can be used to confirm the youth
properties of stars, but are limited by extinction. Thus,
it is difficult to quantify the completeness of our YSO
census. Here, we only qualitatively evaluate it based on
the K-band luminosity function (KLF) of our YSO sam-
ple.
The shapes of KLFs of young clusters are sensitive to
their initial mass functions (IMF) and the mean ages
(Muench et al. 2000), and thus can be used to constrain
these properties (Strom et al. 1993; Lada & Lada 1995;
Muench et al. 2002, 2003). In our YSO catalog, 84% of
the YSOs have been detected in the 2MASS survey. In
Fig. 7(a), we show the KLF of these YSOs. The KLF of
L1641 peaks at ∼12 mag (see Fig. 7(a)), consistent with
the KLFs of ∼1 Myr old clusters (Muench et al. 2000).
As a comparison we also show the KLF (with the K-
band completeness limit of ∼17.5 mag) of the Trapez-
ium cluster which is at an age (∼1 Myr) similar to L1641
(Muench et al. 2002; Hillenbrand 1997). With the as-
sumption that L1641 and Trapezium have a similar IMF,
one would expect they show a similar KLF shape. Thus,
the comparison of the KLFs of L1641 and Trapezium can
be used to qualitatively evaluate the completeness of our
YSO census in L1641.
In general, the KLF of L1641 (see Fig. 7(a)) fits to
that of the Trapezium cluster within the range of 10 to
15 mag, cor responding to a mass ra nge of 1 .0-0.04 M⊙for
1 Myr PMS stars(Dotter et al. 2008; Baraffe et al. 1998).
However, at the faint (&15mag) and bright (8 to 10 mag)
ends of the KLF, L1641 appears to be deficient in the
stars, compared to the Trapezium cluster. The lack of
faint YSOs in L1641 is mainly attributed to incomplete-
ness of the 2MASS survey. In our YSO catalog, there are
16% of the YSOs which are not detected by the 2MASS
survey. These objects can partially contribute to the
faint part of the KLF of L1641. Within the range of
8 to 10 mag, corresponding to intermediate mass 1 Myr
PMS stars (Dotter et al. 2008), there is another defi-
ciency in YSOs, which could be attributed to the fact
that intermediate-mass stars usually show very weak X-
ray emission, and would not be picked up by the XMM
survey (Feigelson et al. 2003). These intermediate-mass
YSOs can be detected in the optical and infrared imag-
ing surveys. But if they have lost their circumstellar
disks, they cannot be identified as YSOs according to
their infrared colors. The comparison of the KLFs of
L1641 and Trapezium suggests our YSO census may lack
∼60 intermediate-mass diskless stars in L1641. Recently,
Hsu et al. (2012, 2013) have proposed that L1641 and the
Trapezium cluster may have different IMFs, and L1641
is deficient in the stars at the upper mass end of IMF,
compared with that of the Trapezium cluster. Thus, the

YSOs in L1641 (hatched histograms) and in the Trapezium cluster

been shifted from 414 pc (Menten et al. 2007) to 450 pc, and scaled
to match the peak of the KLF of L1641. The dashed line marks
the completeness limit of the 2MASS survey. (b) The K-band

actually numbers of missing intermediate-mass diskless
stars in our YSO census may be less than that we ex-
pected.
In Fig. 7(b) we show the KLFs of two populations of
YSOs in our sample: one for the young stars with in-
frared excesses, and the other for those with X-ray emis-
sions. It can be noted that both KLFs are similar when
Ks<12.5 mag, correspo nding to a 1 Myr PMS stars with
masses&0.2 M⊙, though both populations only share the
common 159 stars with Ks<12.5 ma g. At the faint end
of KLF (Ks>12.5 mag), X-ray emitting YSOs are clea rly
deficient in stars compared with the YSOs with infrared
excesses, which could be due to the incompleteness of the
XMM survey. We evaluate the completeness of the XMM
observations in L1641 using the tool, Flux Limits from
Images from XMM-Newton (FLIX)7, which can be used
to roughly estimate the upper limit from the observed
XMM image. We used the FLIX tool to estimate the 5-σ
upper limit of the 0.2– 2 keV X-ray luminosity in the field
of L1641. We found that the 5-σupper limits vary from
region to region with a typical value ∼2.4×1029 erg s−1
at the distance (∼450 pc) of L1641. According to the re-
lation between the X-ray luminosity and stellar mass for
the young stars in Taurus (∼1.5 Myr) from G¨udel et al.
(2007), the typical 5-σupper limit of the X-ray observa-
tions corresponds to the X-ray luminosity of 1.5Myr old
7FLIX is a on-line tool provided by the XMM-Newton Survey
Science Center (see http://www.ledas.ac.uk/flix/flix.html). It pro-
vides robust estimates of the X-ray upper limit to a given point in
the sky where there are no sources detected in the 2XMMi catalog.

algorithm.

PMS star with masses of 0.2– 0.3 M⊙, which is consistent
with the estimate of incompleteness from the KLF of X-
ray sources. In the FOVs of the XMM observations, we
have identified 395 Class I II sources with spectroscopy.
Among them, 253 sour ces are br ighter than 12.5 mag at
Ksband, and ∼78% (197/253) of them show X-ray emis-
sions. The fraction of X-ray emitting sources among the
faint Class III sources (Ks>12.5 mag ) decrease to ∼38%
(54/142). On one hand these statistics confirm the re-
sults on the completeness of the YSOs selected from the
X-ray data estimated using FLIX and KLF; on the other
hand they indicate that the spectroscopic surveys have
partially relieved the incompleteness of Class II I sources
suffered from the X-ray survey.
We estimate the approximate completeness of our YSO
census based on the study of Hsu et al. (2012) in which
the targets for the spectroscopic survey are selected from
Vvs. V−Icolor-magnitude diagram. The spectroscopic
survey of Hsu et al. (2012) is complete to V.21 mag for
disk population, and has ∼95% completeness for disk-
less population till V.21 ma g, which corresponds to a
1.5 Myr old, ∼0.2 M⊙PMS star with AV∼3. The faint
disk population (V&21 mag), most of which are heavily
extincted objects, are below their detection limit, but can
easily be detected in the Spizter imaging survey. In our
catalog, there are 533 Class II sources. Among them, 330
Class II sources are in Hsu et al. (2012). The other 203
Class II sources a re to o faint to be observed. In the s ame
field, Hsu et al. (2012) have found 388 Class III sources.
If we assume that both Class II and Class III sources have
a similar fraction of faint sources, which are unobservable
in the spectroscopic survey of Hsu et al. (2012), the total
number of Class III sources is expected to be ∼660. In
our YSO catalog, 507 Class III sources are inventoried.
Thus, the completeness of our YSO census is estimated
to be ∼90% (1388/1541). In addition, we can evalu-
ate the completeness of our YSO sample using the rvs.
r−icolor-magnitude diagram (see the detail discussion
in Appendix C), and find that our census is complete to
r.20 which corresponds to a 1.5 Myr old, 0.2 M⊙PMS
star with an extinction of AV∼3.
Our YSO catalog may be contaminated by a small
fraction of extragalactic sources and nearby foreground
stars. These contaminators show similar SEDs to those
of YSOs or X-ray emissions, thus are selected as YSO
candidates. The main extragalactic contaminators in-
clude star-forming galaxies and AGNs (Gutermuth et al.
2008). According to the criteria of Gutermuth et al.
(2008), which are used to identify potential extragalactic
contaminators based on the IRAC photometry and col-
ors, 92 among 1273 sources with detection in four IRAC
bands are suggested to be contaminators. Among the
92 “contaminators”, 13 are observed with spectroscopy
and confirmed as young stars, thus excluded as the con-
YSOs in L1641: Disks, Accretion, and SFH. 11
taminators. Among the remaining 79 sources without
spectroscopy, 66 “contaminators” show the SEDs char-
acteristic shape of classI/Flat YSOs, and 13 are clas-
sified as Class II sources. Thus, statistically about 6%
(79/1273) of our YSO candidates could be extragalac-
tic contaminators. This, however, is a conservative es-
timate: a few of these “contaminators” are located at
the dense regions of the L1641 cloud, thus could be real
YSOs. The foreground stars can also contaminate our
YSO catalog. These stars show detectable X-ray emis-
sion, thus being wrongly classified as Class II I sources.
The typical X-ray luminosity of field main-sequence stars
is several×1027 erg s−1for solar-type to M-type main se-
quence stars(G¨udel 2004). According to the 5-σupper
limit of the 0.2–2 keV X-ray luminosity in the XMM sur-
vey of L1641 estimated with FLIX, XMM observations
can detect the field stars within the distance.90 pc. Us-
ing the Besan¸con model of stellar population synthesis of
the Galaxy (Robin et al. 2003), we obtain small numbers
(∼15) of stars within the distance.90 pc in the direction
of L1641, suggesting the faction of contaminators from
foreground stars in our YSO catalog is about 1%.
Recently Alves & Bouy (2012) proposed that there is
a large cluster, NGC 1980, in front of Orion A cloud.
They separated foreground stars and young stars in the
Orion A region based on an assumption that young stars
in Orion A are reddened and foreground stars have neg-
ligible amount of extinction. They found that the fore-
ground sources are mainly centered on NGC 1980. The
extent of their suggested foreground population reach
northern part of L1641, and therefore could contaminate
our YSO sample in L1641. The age of NGC 1980 clus-
ter is estimated to be ∼4–5 Myr, which is much older
than the median age (∼1 Myr) of the stellar popula-
tion in our L1641 sample (Fang et al. 2009, this work).
The Kinematics of the stellar population in NGC 1980
is similar to that of young stars and molecular gas in
Orion A, suggesting NGC 1980 may be physically associ-
ated with Orion A. It is possible that our sample could be
contaminated with older population of NGC 1980, which
could result in older median age and lower disk fraction.
We inspect the contamination of these “old” sources into
our YSO census by comparing the ages of sources with
AV<0.1 and those with AV>0.5. The median ages of the
two samples are 1.6 Myr and 1.3 Myr, respectively. Thus
we expect that the contamination in our YSO sample is
not significant.
4.1.3. Infrared spectral slopes
Figure 8 shows the distributions of the dereddened
spectral infrared slopes, α2−8,α3.6−8,α2−24, and
α3.6−24, for the YSOs in L1641. The disked and disk-
less objects appear in two distinct peaks in four panels in
Fig. 8, although only a few diskless YSOs are detected at
24 microns. As a comparison, in Fig. 8 we also show the
peak positions of such distributions for YSOs in Taurus,
which is at the similar age to L1641. Both star-forming
regions show similar peak positions for the disk popula-
tion, suggesting that the disks are at a similar evolution-
ary stage.
Using the spectral slopes α3.6−8and α3.6−24, we clas-
sify our sources into Class III, Class II, Flat-spectrum,
and Class I and list their types in table 3, according to the
criteria described in Sect. 3.4.1. We have 507 Class II I
sources, 533 Class II sources, 131 Flat-spectrum sources,
and 143 Class I sources. In Fig. 2, we show their spa-
tial distributions. The ratios of Class I to Class II, and
Flat-spectrum to Class II are 0.27 and 0.25, respectively,
comparable to those (∼0.27 and ∼0.20, respectively) in
the Spitzer c2d Legacy survey.

distribution of all the stars with reliable spectral types. The filled
histograms display the YSO distribution. (b) The grey-color filled
histograms show the spectral-type distribution of all known YSOs
with spectral types in L1641. The hatched histograms display the
spectral-type distributions of field stars identified in both works.
4.2. Spectroscopic sample
We have obtained optical spectra for a large sample
of the YSOs in L1641 with Hectospec and Hectochelle.
In this section, we will present the results from these
observations.
4.2.1. Spectral types
We determined the spectral type of each star in our
spectroscopic sample as described in Sect. 3.2. We have
∼400 stars with reliable estimates of their spectral types.
Among them, ∼300 sources are identified as young stars
according to the criteria in Sect. 3.1, and others as field
stars. The spectral types of the YSOs are listed in ta-
ble 4. In Fig. 9(a) we show a histogram of spectral types
for all stars, including field stars and YSOs, in our Hec-
tospec survey. The distribution is bimodal, with peaks
around spectral type G0 and mid-M. In this figure, we
also show the spectral-type distribution of the identi-
fied YSOs. These YSOs are typically K or M type with
few stars earlier than K0 type. We combined the YSOs
and field stars with spectral types in the field of L1641,

The field stars show a bimodal distribution with peaks

circles are for the YSOs in our spectroscopic survey with Hectospec,

the YSOs in Hsu et al. (2012). The star symbols represent the
TDs in L1641. The open diamond marks the new subluminous
object (See Sect. 4.5.2). The PMS evolutionary tracks are from
Dotter et al. (2008).
4.2.2. Stellar masses and ages
With the determined effective temperatures and bolo-
metric luminosities as described in Sect. 3.3, we can
place the young stars in the HR diagram. In Fig. 10,
we show the HR diagrams for the YSOs with spectral
types. Most of our YSOs lie between the 0.1 and 3 Myr
isochrones. We use distinct symbols (open star sym-
bols) for objects with SEDs typical for TDs (see also
Sect. 4.3.1), as well as a new “exotic” object that is ap-
parently under-luminous(see Sect. 4.5.2). In Fig. 11(a),
we show the mass distribution (filled histograms) for the
YSOs in this work, and the mass distribution (open his-
tograms) when adding the YSOs with spectral types in
the literature. The median masses are ∼0.40 M⊙and
0.30 M⊙for the two populations, respectively. A linear
regression fit to the mass functions within the mass bin
−0.5 ≤log(M⋆/M⊙)≤0.5 yields slopes of −1.24±0.13
and −1.50±0.15 for the two populations, respectively.
In Fig. 11(b), we show the age distribution of the sample
two populations as in Fig. 11(a). The median age for the
entire sample is 1.5 Myr.
Lithium depletion trends in young PMS stars can be
used to estimate the stellar ages at sub-solar masses
(Mentuch et al. 2008; Jeffries et al. 2009). In Fig. 12 we
show the equivalent width (EW ) of the Li I λ6 708 ˚

sorption line as a function of spectral type for the YSOs

line for each YSO is derived from the Hectochelle spec-
tra. Some YSOs have been observed at multiple epochs
with Hectochelle and for these YSOs, we show their mean
EW s weighted by the uncertainty in each spectral epoch.
In Fig. 12, the E W s of CTTSs are generally smaller
than those of WTTSs with similar spectral types due to
the veiling effect in which continuum emission from ac-
cretion shocks on the surface of the star can reduce the
measured EW of CTTSs. In Fig. 12 it can be also noted
that the EW of Li I λ6 708 ˚

the age spread in these WTTSs. As a comparison, Fig-
ure 12 also shows the E W s of Li I λ67 08 ˚
A for the YSOs
in Taurus (Sestito et al. 2008), and in L1630N and L1641
presented in Paper I. The L1641 star-forming region is
roughly the same age as Taurus and L1630N, thus it is ex-
pected to show a lithium depletion trend similar to those
in Taurus and L1630N. Using the EW of the Li I λ6708 ˚
A
absorption line for YSOs in the three regions, we esti-
mate the median EW in each spectral-type bin (filled
star symbols in Fig. 12). For the YSOs with spectral
types later than K5, the median E W s generally agree
with the theoretical locus for YSOs with undepleted
Lithium (Baraffe et al. 2002; Jeffries et al. 2009). The
median EW and theoretical locus deviate for the YSOs
with spectral type earlier than K5. The median E W s
for the 1 Myr old population are much larger than those
in the Tucanae-Horologium stellar association, which has
an age of 27±11 Myr (Mentuch et al. 200 8).
4.2.3. Extinction
We estimated the extinction for each individual ob-
ject using the method outlined in Sect. 3.3. The typi-
cal uncertainty for the extinction values is less than 0.1
magnitude. In Fig. 13(a), we show the AVdistribution
of the YSOs (filled histograms) from this works, as well
as all YSOs (open histograms) with spectral types in
L1641. Both populations have a similar AVdistribution
with a peak at very low extinction (AV<1 mag) and a
gradual decrease of YSO numbers towards higher AV.
In Fig. 13(b), we show the field stars (filled histograms)
identified in this work, and all the field stars (open his-
tograms) identified in both this work and Paper I. The
two populations of field stars show a similar AVdistribu-
tion, but different from the AVdistribution of the YSO
samples (see Fig. 13(a)). The AVdistribution of the field
stars has a peak at AV.1 mag consistent with foreground
and background objects along sight lines with low extinc-
tion, and a relatively flat distribution between ∼1 and ∼8
magnitudes of AVwith a peak around AV=4–6 mag.

for the Tucanae-Horologium association with an age of 27±11 Myr
(Mentuch et al. 2008).

Our main TD selection criteria are based on col-
ors as shown in Fig. 6(b): [8.0]−[24]≥2.5 and
Ks−[5.8]≤0.56+([8.0]−[24])×0.15. For the YSOs with
spectral types, we use the spectral types of the central
stars to constrain the photospheric emission. We com-
pare their SEDs with their model photospheric emissions
to look for the sources showing very weak or no infrared
excess at near infrared wavelengths and shorter IRAC
bands, but strong excess emission at mid-infrared and
longer wavelengths.
In Fig. 14, we show the SEDs of the 46 newly con-
firmed TDs in this work. Among them, 40 TDs are se-
lected based on our TD selection criteria (see Fig. 6(b)).
The additional 6 TDs are selected by the comparison
of their SEDs and photospheric emission. Among the
6 TDs, two(#226 and 249) of them show nearly photo-
spheric emission at wavelength out to ∼8µm, and mod-
erate excess at 24 µm ([8.0]−[24]<2). The other 4 TDs
(#971, 1196, 1268, and 1379), showing near-infrared ex-
cess emission significantly reduced from normal T Tauri
stars, are located close to the TD selection boundary.
In the literature, there are several criteria to select
TDs, e.g. Paper I, Mer´ın et al. (2010), Muzerolle et al.
(2010), etc. Our selection criteria, based on Ks−[5.8] and
[8.0]−[24] colors, is displayed in Fig. 6(b). Mer´ın et al.
(2010) provide different criteria based on [3.6]−[8.0]
and [8.0]−[24] colors: (1) 0.0<[3.6]−[8.0]<1.1 and
3.2<[8.0]−[24]<5.3 for classical TDs (with inner holes);
(2) 1.1<[3.6]−[8.0]<1.8 and 3.2<[8.0]−[24]<5.3 for TDs
with weak excess emission in Spitzer IRAC bands.
Muzerolle et al. (2010) employ two infrared spectral
slopes to select TD candidates: (1) −1.5≤α8−24≤0 and
α3.6−5.8≤−1.8 for weak excess TDs; (2) α8−24>0 and
α3.6−5.8≤−1.8 for classical TDs (with inner holes). Our
TD sample in this work is mainly selected using the cri-
teria in Paper I. Including the TDs in Paper I, we have
65 TDs with spectral-type estimates in L1641. Among
them, 64 TDs are detected in all four IRAC bands and
at MIPS 24 µm. We use these 64 TDs to compare
our TD criteria with those from Mer´ın et al. (2010) and
Muzerolle et al. (2010). In Fig. 15, we show how these
TDs fit to the selection criteria from Mer´ın et al. (2010)
and Muzerolle et al. (2010). According to the criteria of
Mer´ın et al. (2010), 38 sources are classified into their
Group (1), and 9 sources are classified into Group (2).
Among the remaining 17 sources which are excluded
as TDs, 16 objects do not show strong enough excess
emission at 24 µm, and one object shows too strong
excess emission at 24 µm (see Fig. 15(a)). These re-
jected sources fall within the criteria of Muzerolle et al.
(2010). According to their criteria, 23 are categorized
into their Group (1), 35 into their Group (2), and 6
sources excluded as TDs but very close to the selec-
tion boundaries. Thus, our selection criteria are gener-
ally consistent with those from Mer´ın et al. (2010) and
Muzerolle et al. (2010).
4.3.2. Globally depleted disks
In Fig. 16, we show the SEDs of the globally depleted
disk candidates in L1641, as well as the median SED
of T Tauri stars in Taurus (Furlan et al. 2006). Com-
pared with the median SED of Taurus, these YSOs in
Fig. 16 show uniformly depleted SEDs with an infrared
excess emission level that has been reduced by a sim-
ilar factor across 3.6 –24 µm. Such SED types can be
produced when disks are deficient in small dust grains
(Currie et al. 2009; Sicilia-Aguilar et al. 2011). For these
disks, their effective disk height, i.e. the height above the
disk midplane where the disk becomes optically thick to
the stellar radiation, can be substantially reduced, caus-
ing a smaller fraction of the stellar energy to be absorbed
and reprocessed by the disk, which produces an infrared
excess emission of reduced magnitude. Dust coagulation
can lead to a deficiency of small dust grains, and the
larger grains couple less efficiently with the gas, allowing
them to settle towards the midplane.
4.3.3. Young debris disks or “evolved” TDs?

(blue), 2MASS (magenta), and Spitzer (red). The open diamonds are the photometry from WISE. The photospheric emission level is
indicated with a grey curve in each panel.
Figure 17 shows the SEDs of two objects #172 and
269. These two sources show essentially photospheric
emission levels at λ.10 µm, but display weak excesses
at 24 µm. This SED shape is typical of “debris disks”
(see, e.g. Carpenter et al. 2009). Such disk system pos-
sess relatively small amounts of circumstellar material
which are produced in the collisional grind-down of larger
bodies (“planetesimals”). In Fig. 17, both of the stars
have the spectral type K6, and show X-ray emission
(see table 2). Their ages, estimated from different sets
of PMS evolutionary tracks, are all less than 1 Myr
(see table 5). The youth of the stars #172 and #269
can be further confirmed by our spectroscopic observa-
tion. The star #172 has been observed with both Hec-
tochelle and Hectospec and both spectra clearly show
Li I λ6708 ˚
A absorption line. In its high-resolution Hec-
tochelle spectrum, the EW of the Li I λ6708 ˚
A absorp-
tion line is 0.53 ˚
A. The star #269 has only been observed
with Hectospec. In its Hectospec spectrum, the EW of
the Li I λ670 8 ˚
A absorption line is ∼0.5 ˚
A. The Li E W s
of both stars suggest they are as young as other YSOs
in L1641 (see Fig. 12). Furthermore, the star #172 has
a radial velocity VLSR=5±2 km/ s (relative to the lo cal
standard of rest) similar to the local molecular gas in
L1641 (Bally et al. 1987), suggesting the star #172 is
physically associated with the L1641 cloud.
In the case that the disks are optically thin through
24 µm we can estimate the timescale for small dust grains
removed by Poynting-Robertson drag using the method
described in Currie et al. (2009). For 10 µm dust grains
with a volume density (ρs)∼1 g cm−3, and an absorption
coefficient (hQabsi)∼1, the Poynting-Robertson drag can
remove these grains on timescales.6×105yr. When the
dust grains are porous, the drag time could be much
shorter (Currie et al. 2009). For the two stars, the
typical grain sizes, below which the radiation pressure
can remove dust from the system, are estimated to be
∼3–8 µm using the Equation (4) in Currie et al. (2009)
with ρs∼1 g cm−3, and hQabsi∼1. However, whether the
Poynting-Robertson drag can work on dust grains also
depends on the coupling of dust to the gas. If the gas
density in circumstellar disks is low, the dust grains emit-

and (b) Muzerolle et al. (2010). The filled circles are our con-
firmed TDs in L1641 from both Paper I and this work. In panel
(a), classical TDs (with inner holes) lie within 0.0<[3.6]−[8.0]<
1.1 and 3.2<[8.0]−[24]<5.3, and TDs with weak excess emis-
sion in Spitzer IRAC bands lie within 1.1<[3.6]−[8.0]<1.8 and
3.2<[8.0]−[24]<5.3. In panel (b), the region with −1.5≤α8−24≤0
and α3.6−5.8≤−1.8 are for weak excess TDs, and the region with
α8−24>0 and α3.6−5.8≤−1.8 for classical TDs.
ting the 24 µm excess emission can be quickly removed
at the above dynamical timescale without the replenish-
ment by the collision of larger planetesimals. Thus the
disks around the two stars #172 and 269 could be debris
if they are at ages of several Myr. However, the ages
of the stars #172 and 269, estimated from different sets
of PMS evolutionary tracks, are all younger than several
105yr. If their isochrone ages are reasonable, it is also
possible that the two sources are relatively evolved TDs
with much larger inner holes (several ten AU) in the disks
than normal TDs. Such type of evolved disks could be
still gas rich, and only produce weak excess emission at
24 µm.
4.4. Accretion
The Balmer emission lines in the spectra of PMS stars
can be produced in two ways: chromospheric activity
and magnetospheric accretion. The former mechanism
usually yields weak and narrow emission lines, while
the magnetospheric accretion process can produce very
broad and strong emission lines (Hartmann et al. 1994;
Muzerolle et al. 2001; White & Basri 2003). Thus, the
strength and width of the Balmer emission lines, espe-
cially for the Hαline, are used to characterize the ac-
cretion activity of young stars. Our Hectospec spectra
cover both the Hαand Hβlines with a medium spectral
resolution, and the Hectochelle spectra cover the Hαline
with a high spectral resolution. We will use all these data
to study the accretion properties of young stars.
4.4.1. Characterizing accretion activity with
medium-resolution spectroscopy
We classified the YSOs into weak T Tauri stars
(WTTS) or CTTSs based on their Hα EW in the Hec-
tospec spectra using the spectral type dependent criteria
described in Paper I. A star is considered to be a CTTS
if EW (Hα)≥3˚
A for K0–K3 stars, E W (Hα)≥5˚
A for
K4 stars, E W (Hα)≥7˚
A for K5–K7 stars, EW (Hα)≥
9˚
A for M0–M1 stars, E W (Hα)≥11 ˚
A for M2 stars,
EW (Hα)≥15 ˚
A for M3–M4 stars, E W (Hα)≥18 ˚
A for
M5–M6 stars, and EW (Hα)≥20 ˚
A for M7–M8 stars.
These criteria are based on the Hαline E W s, which
makes them useful for spectra with low spectral resolu-
tion. The disadvantage of this definition is that it may
misclassify some accretors as WTTSs. In our spectro-
scopic sample observed with Hectospec, a few of the
YSOs (e.g. ID#23 and 36) have been observed with
Hectochelle, and show broad Hαline profiles, indicat-
ing an ongoing accreting activities despite the small Hα
EW . The Hαline EW s of these sources are below
the thresholds to be classified as CTTSs because of the
strong absorption around their Hαline centers. In this
case, we also use the velocity width at 10% maximum
height (F WHα,10%) of the Hectochelle spectra to dis-
tinguish the CTTSs and WTTSs. As discussed in the
Appendix A, a YSO can be classified as a CTTS if its
F WHα,10% >250 km s−1.
In table 4, we list the E W s of Hαand Hβfrom the Hec-
tospec spectra for our YSO sample, and their accretion
properties, i.e. CTTS or WTTS. For the CTTSs, we esti-
mated their accretion rates from the Hαand Hβline lu-
minosity using the metho ds described in Sect. 3.4.2. The
results are also listed in table 4. The typical uncertain-
ties are a factor of ∼5 for the accretion rates derived from
Hαline luminosity, and a factor of ∼3 for those from Hβ.
For the WTTSs with disks, only upper limits on the ac-
cretion rate, estimated with Hαand Hβline luminosity
as done for CTTSs, are given since their Balmer emis-
sion is mainly due to the chromospheric activities. In
table 4, the disk property of each YSO is also listed. For
the normal full disks, the disks categorized into optically
thick disks if α3.6−8≥ −1.8, or optically thin disks when
α3.6−8<−1.8.
4.4.2. High-resolution Hαspectroscopy
We obtained the Hαemission lines for 235 young stars
in L1641 with Hectochelle. In this sample, 8 objects are
Class I/Flat sour ces, 102 are Class II sources, a nd 124
are Class III sources. One ob ject (#385) in the sample
cannot be classified due to the lack of photometric data
in infrared bands. During 2010-2011, a ma jor fraction of
these YSOs have been observed at two or three epochs In
table 6 we list the EW and F WHα,10% of the Hαemission
line, EW of Li I λ6708 ˚
A absorption line, types (CTTS or
WTTS) of T Tauri stars, and the accretor probabilities.
The accretor probabilities are estimated from F W Hα,10%
using the method described in Appendix A. The accre-
tion rates estimated from the F W H α,10% are also listed
in table 6.
Many of the YSOs in our Hectochelle sample have been
observed in our medium-resolution spectroscopic survey

with VIMOS and Hectospec (in Paper I and this work).
In Fig. 18, we compare the Hα E W s from Hectochelle
and those from VIMOS or Hectospec. We find that there
is a better agreement between these observations for Hα
EW .10 ˚
A than for Hα EW &10˚
A. This can be at-
tributed to the accretion variability of accreting YSOs
which usually show Hα EW >10 ˚
A.
4.4.2.1. Hαemission profiles
In Fig. 19, 20, 21, 22, 23, we display the Hectochelle
Hαline profiles for the disk population in our spectro-
scopic sample. For the sources which have been observed
at multiple epochs, all the data are shown as a compar-
ison. In general, most of these line profiles can be clas-
sified into the four groups according to the schemes in
Reipurth et al. (1996): (I) profiles with a single peak and
no or very weak absorption features; (II) profiles with two
relatively equal peaks; (III) profiles with one primary
strong peaks and one weak secondary peak; and (IV)
P Cygni or inverse P Cygni profiles. In our YSO sample,
the type I Hαline profiles are either narrow or broad,
while the type II and III profiles are typically broad. We
only have one source (ID#136, see the detail description
of this sources in Sect. 4.5.3) showing a P Cygni profile
(Type IV). One source (ID#69) shows a triple-peak pro-
file on 2010-03-03 and cannot be classified into any of the
four groups in Reipurth et al. (1996).
In our spectroscopic sample observed with Hectochelle,
there are 33 TDs. Their Hαline profiles are shown in
Fig. 19. Among the 33 TDs, ∼42% show broad Hα
line profiles (F W Hα,10%>250 km s−1), characteristic of
ongoing accretion. Among the TDs showing broad Hα
line profiles, 5 sources (ID#23, 36, 195, 202, and 381)
display Hαline profiles with double peaks from the data
observed at all epochs. As defined in this work, TDs show
very weak or no excess emission in shorter IRAC bands.
The absence of excess emission at such wavelengths can
be explained if (1) TDs have dissipated most or all of the
hot inner disks, or (2) in the inner regions of TDs there
are opacity holes due to a lack of small dust grains, while
gas still exists in these regions. For the accreting TDs in
our sample, the scenario (1) can be excluded.
In Fig. 20, we show the line profiles for the disk pop-
ulation with α3.6−8≥ −1.0. These sources have strong
excess emission in the IRAC bands, thus are expected
to show strong and broad Hαline profiles. In the fig-
ure, ∼83% of the sources display the broad line pro-
files (F W Hα,10% >250 km s−1) at one epoch. Five sources
(ID#31, 66, 314, 462, and 599) exhibit relatively narrow
line profiles at and these sources may have more quies-
cence accretion activities.
In Fig. 21 and 22, we show the line profiles for the
sources with −1.0>α3.6−8≥ −1.8. These sources are
typical Class I I sources with optically-thick inner disks.
In this sample, ∼80% of the sources show broad Hα
line profiles(F W Hα,10% >250 km s−1) at one epoch. In
Fig. 23, we display the Hαline profiles of the YSOs with
−1.8>α3.6−8≥−2.5. The YSOs with such αvalues are
considered as having optically thin inner disks. How-
ever, four sources (ID#16, 54, 138, and 162) still show
very broad Hαline profiles (F W Hα,10% >250 km s−1),
suggesting that they are still accreting.
4.4.2.2. Hαline variability
Hαline profile fluctuations are very common in
CTTSs, and can be due to the variability of accre-
tion flow or outflow(Johns & Basri 1995; Gullbring et al.
1996; Alencar et al. 2001; Alencar & Batalha 2002). In
our sample, ∼90 diskless YSOs and ∼80 disked YSOs
have had their Hαline profiles monitored at multiple
YSOs in L1641: Disks, Accretion, and SFH. 17

epochs with Hectochelle. The Hαemission-line varia-
tions of WTTSs are mainly related to the chromospheric
activity, and are less variable than the CTTS . In this
work, we will only focus on the CTTSs. In our sam-
ple, most of CTTSs show clear variations in their Hα
line profiles. Among them, several sources, e.g sources
ID#20, 26, 69, etc, exhibit extreme line variations. The
Hαline fluctuations (see Fig. 19, 20, 21, 22, and 23) can
be mainly grouped into several types: (1) Hαline profiles
vary from single peak to double peak, or even to triple
peaks, e.g. the sources ID#26, 69, 339, etc., (2) the peak
positions vary, e.g. the sources ID#93, 110, 195, etc., (3)
the ratio between two peaks of Hαlines varies, e.g. the
sources ID#343 and 381, (4) Hαline profiles broaden or
narrow, e.g. the sources ID#19, 21, 86, etc. The Hα
line variation of one YSO can usually be classified into
more than one group. For the YSOs which can be cat-
egorized into the group (4), their Hαline variations are
mainly due to their accretion variations. Especially, two
sources in our sample (ID#26 and #86) show large vari-
ability from CTTS (F W Hα,10% >250 km s−1) to WTTS
(F W Hα,10% ≤250 km s−1).
A few of the sources in our Hectochelle sample have

ison, we show these observations in Fig. 19, 20, 21, 22,
and 23. The spectral resolution of the VIMOS spectra
is ∼2500 and the data can only resolve relatively broad
Hαline profiles. The comparison shows that the sources
ID#69, 344, and 470, exhibit large variations in Hαemis-
sion line.
4.5. Exotic objects
4.5.1. Extremely embedded sources
In the [3.6]−[4.5] vs. [5.8]−[8.0] color-color diagram
(see Fig. 6(a)), five objects (ID#1074, 1218, 1220, 1233,
and 1244) have colors distinct from the other sources.
Their colors ([5.8]−[8.0]∼0 and [3.6]−[4.5]>1.0) make
them appear as diskless stars with extremely high extinc-
tion (AK&10). Among the five sources, four (ID#1074,
1220, 1233, and 1244) are in the FOVs of the XMM sur-
veys, and only ID#1074 is detected. In the Spitzer IRAC
images, four sources (ID#1218, 1220, 1233, and 1244)
are surrounded by extended emission with fan-shaped
structures (see Fig. 24), and only the source ID#1074
appears as a point source without any nebulosity. The
source ID#1074 is not detected in the MIPS 24 µm im-
ages. Thus we consider it as a highly reddened diskless
stars. The four sources associated with fan-shaped neb-
ulae are all detected at 24 µm, and show strong excess
emission in this band with [8.0]−[24]&7, indicating they
could be at a very early stage in the star-formation pro-
cess. The fan-shaped nebulae around these sources are
most easily explained by the scattering of photons from
the central star out of cone-shaped cavities which are

carved out of the dense envelope by energetic outflows.
Furthermore, near ID#1244 we find bipolar jets traced
by the Spitzer 4.5 µm emission 8. The morphology of the
jets suggests ID#1244 could be its driving source.
We have searched for the five sources in the Hub-
ble space telescope (HST) data archive. Two objects
(#1233 and 1244) have been observed with HST/WFC3
at F160Wband, and are not detected in these images.
8The Spitzer 4.5 µm band cover several H2lines (µ=0–0,S(9, 10,
11)), which could be excited by the interaction of the outflows with
the ambient medium. Thus the Spitzer 4. 5 µm image are used to
search for the jets from young stars (see e.g. Zhang & Wang 2009).
The source #1220 has been observed with HST/NIC2 at
F160Wand F205Wbands. In addition to continuum
emission, the broad bands F160Wand F205Wprinci-
pally transmit the [Fe ii] 1.644 µm and H22.122 µm lines,
respectively both of which can originate from shocked
gas. In the HST images at both F160Wand F205W
bands, the object #1220 shows a cometary shape with
a bright head and a long tail. Fig. 25 shows the
F205Wimage of #1220. Two scenarios can explain the
shape of #1220 in the HST images: (1) a young stellar
system photoevaporated by nearby massive stars, e.g.
like proplyds (O’dell et al. 1993; Brandner et al. 2000;
YSOs in L1641: Disks, Accretion, and SFH. 19

Fang et al. 2012), or (2) a YSO producing a jet which
appears as a long tail. For the object #1220, the former
scenario can be excluded since there are no massive stars
near #1220. The latter scenario could be a promising
explanation for the shape of #1220 in the HST images.
4.5.2. A new subluminous object
In the HR diagram (see Fig. 10), one source (ID#143)
appears to be subluminous by a factor of ∼110 with re-
spect to a 1 Myr PMS star of a similar spectral type.
Its optical spectrum and SED is shown in Fig. 26.
In its optical spectrum, the Hαemission line seems
to be quite strong. Objects with similar properties
have been found in many regions e.g. L1630N, Lu-
pus 3 dark cloud, and Taurus (Paper I, Comer´on et al.
2003; White & Hillenbrand 2004). Typically these ex-
otic objects show abnormally large Balmer line E W s,
and normal E W s of He I 5876 ˚
A, and the Ca II near-
infrared triplet (8498, 8542, and 8662 ˚
A) (see Paper I;
Comer´on et al. 2003). One likely scenario for these exotic
objects is that they are harboring flared disks with high
inclinations. In this case, the stellar photospheric light
is largely absorbed by the material in the cold, flared
outer disk. The light that we can see mainly comes
from the photon scattering off the disk surface, there-
fore much reduced. The optical emission lines with large
EW s, e.g. Balmer lines and forbidden oxygen emission
lines, may arise in an outflow or disk wind whose scale is
much larger than the central star allowing at least part of
the line flux to reach us relatively unscreened. Emission
lines like He I 5876 ˚
A, and the Ca II near-infrared triplet
(8498, 8542, and 8662 ˚
A) that mainly form in the mag-
netospheric infall flows, close to the central stars, should
be as obscured as the photospheric continuum.
We employ the SED fitting tool of Robitaille et al.
(2007) to fit the SED of ID#143. We excluded models
with stellar spectral types more than two subclass differ-
ent from the observation, and defined the good-fit models
as the models with χ2−χ2b est<2ndata, where χ2best is the
χ2of the best-fitting model, and ndata is the number of
data points for the fits. We obtained two good-fit models
(Model IDs: 3002401 and 3002775) which are shown in
Fig. 26(b). The disk inclination angles of both models are
∼87◦which supports the hypothesis that the sublumi-
nous objects are harboring disk systems with high incli-
nations. The SED fits also give a better constraint on the
stellar luminosity of ID#143. From the stellar luminos-
ity, in combination with the stellar effective temperature
from the optical spectrum, its mass and age is estimated
to be 2.0–2 .2 M⊙and 0.4–0.6 Myr from D08 tr acks, 2.6–
2.7 M⊙and 1 .3–1.8 Myr from S00, 1.8– 2.0 M⊙and 0.4–
0.6 Myr from DM97, and 1.9 M⊙and 1.7–2.4 Myr from
Pisa11. These age estimates are comparable to the ages
of other YSOs in L1641 from each PMS evolutionary
model.
Though the two good-fit models generally follow the
shape of the observed SED of ID#143, they fail to fit
the 10 µm silicate feature (see Fig. 26(b)). The observed
10 µm silicate feature of ID#143 is seen in emission, sug-
gesting that its disk inclination should be substantially
different from 90 degrees (edge-on) since the edge-on disk
system usually show the 10 µm silicate feature in absorp-
tion (Pontoppidan et al. 2005). More detailed models as
well as observations are required to better constrain the

nature of the object ID#143.
4.5.3. The FU Ori type object candidate
The source ID#136 is one of the most interesting
YSOs in our sample. It shows a P Cygni profile in
the Hαline in all of our spectra observed with VI-
MOS, Hectochelle, and Hectospec (see Fig. 20). In
Paper I, we proposed this object as an FU ori can-
didate. This object has been further investigated in
Caratti O Garatti et al. (2012). It shows a 10 µm silicate
feature in absorption (Caratti O Garatti et al. 2012),
suggesting it is probably a Class I protostar. This
source also shows a blue-shifted He I line in absorption
(Caratti O Garatti et al. 2012), a characteristic feature
of FU ori objects (Connelley & Greene 2010). However,
the non-detection of absorption features of the CO band-
head lines longward of 2.29 µm make this source less
likely to be of the FU Ori type (Caratti O Garatti et al.
2012). We have collected the near-infrared photomet-
ric data of ID#136 in the literature (Strom et al. 1989a;
Chen & Tokunaga 1994; Skrutskie et al. 2006). The
data span epochs from 1985/1986 to 2009 during which,
the Kmagnitudes of the source range from 8.14 to 8.39.
Thus it seems that ID#136 did not show big change on
its brightness, which furthermore argue against it as a
FU Ori type object.
5. DISCUSSION
5.1. Disk Evolution
5.1.1. Disk frequency
In the YSO catalog of L1641, 1314 sources can be
grouped into one of the four classes, i.e. Class I, Flat-
YSOs in L1641: Disks, Accretion, and SFH. 21

spectrum, Class II, and Class III. The TDs in our sam-
ple are considered as Class II sources. We calculate
the disk fraction as N(II)/N(II + III), where N(II) and
N(III) are numbers of Class II and Class III sources, re-
spectively, as done for Taurus by Luhman et al. (2010).
The disk fraction of our YSO sample is estimated
to be ∼51±2% (533/1040). If we only count the
YSOs with X-ray emission, the disk fraction is ∼36±3%
(166/466). The lower disk fraction among the X-ray
emitting YSOs, compared with the whole YSO sample,
may be due to that the XMM observations detect more
Class III sources than Cla ss II sources since X-ray ob-
servation is more sensitive to the former than the latter
(Feigelson & Montmerle 1999). As shown in Fig. 2, there
is a slight difference on the FOVs of the XMM survey and
Spitzer survey. If we only count the YSOs within the
common observed regions of both surveys, the disk frac-
tion is ∼51±2% (448/884) for all the catalogued YSOs,
and disk fraction is ∼49±3% (278/567) for “bright”
YSOs (Ks≤12.5 mag). As discussed in Sect. 4.1.2, the
census of diskless population with XMM data is rela-
tively complete for Class III sources with Ks≤12.5 mag,

and become very incomplete for fainter sources. Thus,
we may expect a much higher disk fraction for all the
catalogued YSOs than the one for the brighter YSOs
(Ks>12.5 mag). However, we do not see a significant dif-
ference on the disk fractions for the two populations. In
this work, ∼460 Class III sour ces are identified from sev-
eral spectroscopic surveys (Allen 1995; Hsu et al. 2012,
Paper I and this work). These surveys have selected YSO
candidates for observations partially from the optical
color-magnitude diagrams. In these surveys, more than
200 Class III sources without X-ray emissions have been
identified, which alleviate the incompleteness of Class III
sources in our YSO census suffered from the XMM sur-
vey. In general, we conclude that disk fraction in L1641
is ∼50%.
The disk fraction in L1641 is slightly lower than that
in Taurus (59±4%) which is at a similar age to L1641
(Luhman et al. 2010). In Taurus, most of YSOs have
been observed with mid-IR spectroscopy, which can be
used to distinguish the YSOs with envelopes from those
without envelopes (Furlan et al. 2006). Using these data,
59% of the “Flat-spectrum” YSOs are classified into
Class II (Luhman et al. 2010). Assuming that the same
fraction of the “Flat-spectrum” YSOs in L1641 is actu-
ally Class II sources, the disk fraction in L1641 would
increase to 54±2%, which is generally consistent with
that in Taurus (59±4%).
Furthermore, in L641 we have found 73 TDs. Among
them, 65 have been confirmed and 8 are TD candidates.
The TDs count for 14% of the disk population (Class II)
in our YSO sample. Under the assumption that Class II
lifetime is 2 Myr, the lifetime of TDs is estimated to be
∼0.3 Myr.
5.1.2. Disk frequency as a function of stellar masses
In our sample young stars, more than 800 sources have
been observed with spectroscopy, thus their mass esti-
mates are relatively reliable. For the other ∼200 YSOs
without spectral types, we derived masses from their
dereddened J-band photometry via the theoretical re-
lation between stellar mass and the J-band photometry
YSOs in L1641: Disks, Accretion, and SFH. 23

for PMS stars at an age of 1.5 Myr (the median age of
YSOs in L1641) from Dotter et al. (2008). In Fig. 27 we
show the disk frequency as a function of stellar mass for
five groups of YSOs9: (1) all YSOs with estimates of
stellar masses from either spectroscopy or J-band pho-
tometry, (2) all YSOs observed with spectroscopy, (3) all
YSOs within the common regions covered by the XMM
and Spitzer surveys (See Fig. 2), (4) the YSOs among
Group 3 with spectroscopy, and (5) the YSOs with X-
ray emission. As shown in Fig. 27, the trends of disk
frequency with stellar mass for the YSOs of groups 1-4
are similar, and their disk frequencies are almost con-
stant as a function of stellar masses with a slight peak at
log(M∗/M⊙)≈ −0.25. The disk frequencies of the YSOs
with X-ray emission are lower within the sub-solar mass
range than those of Group 1–4, and generally increases
with the increasing stellar masses, which may be because
that the X-ray observations are very inefficient in detect-
ing the very low-mass disked YSOs.
The trend of disk frequency with stellar mass in this
work is different from our finding in Paper I, in which the
disk frequency increases with increasing stellar mass. In
Paper I, we used a limited sample (∼260) of YSOs, only
including the spectroscopic YSOs, to construct the disk
frequency vs. stellar mass relation. In this work, the
combination of the XMM and Spitzer imaging surveys
make our study less biased. As a comparison, in Fig. 27
we also show relations between the disk frequency and
stellar mass for YSOs in IC 348, Chamaeleon I, and Tau-
rus (Lada et al. 2006; Luhman et al. 2008, 2010). The
trend in L1641 that we identify is quite different from
that seen in Taurus(Luhman et al. 2010), or in 2 Myr old
Chamaeleon I (Luhman et al. 2008). In these regions,
9The mass bins used are, in log(M∗/M⊙), −1 to −0.5, −0.5 to
0, and >0.
the disk frequency increases with the stellar mass. In
the somewhat older IC 348 (see Fig. 27), the disk fre-
quency shows a decreasing trend with stellar mass. A
similar trend has also b een found in the Cep OB3b clus-
ter (3–5 Myr Allen et al. 2012). The trend of disk fre-
quency with stellar mass in L1641 is different from any
of the above regions. To interpret the different trends
of disk frequency with stellar mass in these regions, one
may need to know the disk properties around young stars
with different masses, the star formation history, and the
local environment in each region.
5.1.3. Disks around very low mass stellar/substellar objects
In our spectroscopic sample, there are 3 young brown
dwarfs (#340, 396, and 402) according to the evolution-
ary tracks from Baraffe et al. (1998). Among them, the
source #404 harbors a circumstellar disk. For the sources
without spectral types, we use the Hvs. H−Kscolor-
magnitude diagram (Fig. 28) to select very low mass
stellar/substellar objects by comparing with the theo-
retical PMS isochrone. The ages of spectroscopic YSOs
in L1641, estimated with the evolutionary tracks from
Baraffe et al. (1998), show a broad distribution with a
median age ∼2 Myr. In the figure, we also display the
2 Myr PMS isochrone (Baraffe et al. 1998). We select
very low mass object candidates which are below the
reddening vector of a 2 Myr old, 0.1 M⊙PMS star in the
Hvs. H−Kscolor-magnitude diagram, and find 161
sources. In this sample 115 sources have spectral-type
estimates in the literature, and 50% of them have spec-
tral types later than M5, and 83% of then are later than
M4, suggesting a ma jor fraction of our selected candi-
dates are really very low mass objects. Among the 161
very low mass stellar/substellar object candidates, the
disk fraction is 47% (76/161), which is consistent with
that we found for all the YSOs in L1641.
Figure 29 shows the SEDs of two brown dwarf can-
didates (#541 and 941) with disks. The masses of the
two sources are estimated to be ∼0.04 M⊙using the 2 Myr
PMS isochrone from Baraffe et al. (1998) in Fig. 28. The
SEDs of the two sources are fitted using the online fit-
ting tool provided by Mayne et al. (2012). The fitting
tool employs a set of parameters including stellar mass,
accretion rate, disk mass, etc. (see detailed description
in Mayne et al. 2012). When fitting the SEDs, we fix the
stellar masses to be 0.04 M⊙, and free other parameters.
In Fig. 29 we show the 10 best fitting model SEDs for
each source. Among the top 10 best-fitting models, the
fitted ages of the two sources are both 1 Myr, and the disk
radii are around 100-300 AU. From the fitting, the disk
around the source #541 may have a higher inclination
angle (40◦-60◦) and lower mass (4×10−4–4×10−5M⊙)
than that of the source #944 in which the disk is almost
face-on, and the disk mass is ∼4×10−4M⊙.
5.1.4. Ages of the different populations
According to traditional low-mass star formation the-
ory, CTTSs evolve into WTTSs as circumstellar disks
dissipate. Thus, one would expect that WTTSs are older
than CTTSs. However, the observations of many star
forming regions do not support this theory (Herbig 1998;
Hartmann 2001; Herbig & Dahm 2002; Dahm & Simon
2005), and there are only a few cases in which the WTTSs
are found to be older than CTTSs (Hartigan et al. 1995;

Bertout et al. 2007). In Paper I, we showed that the
WTTSs without disks are statistically older than CTTSs
in L1641, though both show age distributions with
large spreads. In this work, instead of classifying the
YSOs into CTTSs or WTTSs when comparing their age
distributions, we divide the YSOs into three groups:

YSOs in L1641: Disks, Accretion, and SFH. 25
YSOs with optically-thick disks, TD objects, and disk-
less YSOs. In this analysis we include both YSOs from
this work and from Pap er I.
The age distributions of the three populations are
shown in Fig. 30. The median ages of the YSOs with
optically-thick disks, transition disk ob jects, and disk-
less YSOs are ∼1.1 Myr, ∼1.5 Myr, and ∼1.8 Myr, re-
spectively. Though the median ages of different popu-
lations increase with their evolutionary stages, each of
them shows a very broad distribution. A Kolmogorov-
Smirnov (KS) test reveals a relatively low probability
(P∼3×10−6) for the optically-thick disks and diskless
YSOs to be drawn randomly from the same age distri-
bution. The probability that the TDs and diskless YSOs
are drawn randomly from the same population is also low
(P∼0.02), whereas the age distributions of the optically-
thick disks and TDs are less indistinguishable (P∼0.2).
Fig. 30 shows that 34% of the diskless YSOs have
ages less than 1 Myr. Here, the presence of a disk
around a YSO is determined by the excess emission
at infrared wavelengths .24 µm, which is only sensi-
tive to the disk at several AU to tens of AU, depend-
ing on the effective temperature of central stars. A
few of these “diskless” YSOs may still have disks but
with large inner holes. If these YSOs are really diskless
or harbor disks with big inner holes, then there must
be an efficient mechanism to dissipate the inner disks.
In Fig. 30, the age distribution of the TDs hint that
there may be bimodality with one relatively flat distri-
bution at age .1 Myr, and one peak at ∼2 Myr. The
two populations of TDs are more clearly distinguished
in the HR diagram (see Fig. 10). The “young” TDs
(<1 Myr) require a fast mechanism to dissipate the in-
ner regions of their disks. One promising mechanism
could be the interaction between the disk and a close bi-
nary (Lin & Papaloizou 1993). The tidal interaction be-
tween the disk and a close companion can quickly clear
away the material from the binary orbit, form a gap in
the disks, and finally terminate the accretion from the
outer disk to the inner disk (Lin & Papaloizou 1993),
thus accelerating the disk destruction process. Surveys
toward nearby field G and M type dwarfs have found
about 50% of them have companions, with separation
peaking at tens of AU (Fischer & Marcy 1992). Fur-
thermore, surveys towards star forming regions have re-
vealed the binary fraction to be even higher than in the
field (Ghez et al. 1993; Leinert et al. 1993; Ghez et al.
1997; Lafreni`ere et al. 2008). In general, such a high
fraction of close binaries can explain these young disk-
less YSOs or TDs. However, the recent near-infrared
interferometric observations of five TDs in Taurus have
excluded the possibility of having a companion with a
flux ratio ≥0.05, and a separation ranging from 0.35–
4 AU (Pott et al. 2010). Alexander & Armitage (2009)
have proposed that young TD formation can be due to
planet formation, while older ones could be formed due to
photoevaporation, which works in disks with substantial
evolution. Sicilia-Aguilar et al. (2011) show that many
TDs in the 4 Myr old cluster, Tr 37, can be due to grain
evolution. Thus, a bimodal behavior in the age distribu-
tion of TDs is expected.

In Fig. 31, we show the average α3.6−8of the disk
population in several star-forming regions vs. their
ages. The regions include NGC 2068/2071 (∼1 Myr,
Paper I), L1641 (∼1.5 Myr, Paper I and this paper),
Taurus (∼1.5 Myr, Luhman et al. 2010), NGC 1333
(∼2 Myr, Winston et al. 2009, 2010), Cha I (∼2 Myr,
Luhman et al. 2008), IC 348 (∼2.5 Myr, Lada et al. 2006;

2007a), Tr 37 (∼4 Myr, Sicilia-Aguilar et al. 2006b), and
NGC 2362 (∼5 Myr, Currie et al. 2009). We separate the
disk population into two groups according to the spec-
tral types of their central stars. For σOri, NGC 2362,
and NGC 1333, there are no available spectral types
in the literature for most of their members and we
use their J-band magnitude to estimate their spec-
tral types using the isochrone at their corresponding
ages. In Fig. 31 a clear trend of α3.6−8decreasing
with age can be noted for each spectral type range,
as noticed in Sicilia-Aguilar et al. (2006b). The aver-
age α3.6−8decreases slowly over the fir st 3–4 Myr with
most of disk population harboring optically-thick inner
disks (α3.6−8>−1.8). A fast decrease in the average
α3.6−8can be noted for the cluster NGC 2362 at an age
of ∼5 Myr.
5.1.6. The two paths of protoplanetary disk evolution
Spitzer surveys of young clusters, such as IC 348,
NGC 2362, ηCha, the Coronet cluster, and Tr 37 sug-
gest that there are qualitatively two evolutionary paths
for disks progressing from a primordial disk to a de-
bris disk: (1) radially depleted disks, and (2) glob-
ally depleted disks(Lada et al. 2006; Sicilia-Aguilar et al.
2008, 2009, 2011; Currie & Kenyon 2009; Currie et al.
2009). Each path can be distinguished based on their
SEDs. The radially depleted disks show little or no ex-
cess emission in the shorter IRAC bands, but strong ex-
cess emission at 24 µm, suggesting that they are dissi-
pating in an inside-out fashion. The globally depleted
disks show more or less uniformly reduced infrared ex-
cess emission compared to primordial disks over all wave-
lengths out to 24 µm. This indicates that there is
a reduction in their effective disk height for lack of
small dust grains in disks (Currie & Sicilia-Aguilar 2011;
26
Figure 31. The mean spectral slope α3.6−8of the disk population
in different star-forming regions vs. their ages. Panel (a) is for
young stars with spectral type of K7-M3, and Panel (b) is for
young s tars with spectral type of M3- M6. Cha I and Tr37 are
missing from panel (a) and (b), respectively, due to the lack of
members within those spectral type ranges.
Sicilia-Aguilar et al. 2013). The reduced disk height can
decrease the fraction of the stellar energy that is ab-
sorbed and reprocessed by the disk, which results in an
SED with reduced infrared excess.
In Fig. 32, we show the dereddened spectral slopes
α3.6−8and α5.8−24 for the YSOs in L1641. For the
sources which are undetected at 24 µm, the 24 µm up-
per limits are used to calculate α5.8−24. As a com-
parison, we also show the YSOs in several older clus-
ters, σOri (∼3 Myr, Hern´andez et al. 2007a) ,NGC 2362
(∼5 Myr Dahm & Hillenbrand 2007), λOri (∼5 Myr,
Hern´andez et al. 2010), and Ori OB1 Association (∼5-
10 Myr Hern´andez et al. 2007b). As discussed above,
the two disk evolution processes can be distinguished
by their SEDs, which can be quantified by their spec-
tral slopes. For the radially depleted disks, one would
expect α3.6−8decreases while α5.8−24 increases due to
the reduced fluxes at 5.8 and 8.0 µm. With the dissi-
pation of the inner disk regions, α3.6−8will be photo-
spheric, and then as the outer disk is removed α5.8−24
starts to decrease. In globally depleted disks α3.6−8and
α5.8−24 decrease simultaneously. In Fig. 32, the evolved
disks (α3.6−8<−1.8) are distributed around the triangle
(marked by three arrows), which can clearly explained
by the two paths of disk evolution as described above.
5.2. Accretion
5.2.1. Why are accretion rates related to stellar masses?

the YSOs in L1641 with 24 µm detections. The open circles with
arrows are YSOs in L1641 without 24 µm detections. The upper
limits at 24 µm were used to calculate α5.8−24. The YSOs in the
relatively older clusters σOri (op en boxes), NGC 2362 (op en trian-
gles), Ori OB1 Association (open diamonds), and λOri (crosses)
are also shown. The big arrows mark two possible paths for disk
evolution. The arrows (a) and (b) show the path for radially de-
pleted evolution, and the arrow (c) display the path for globally
depleted evolution. The disks that appear in the grey-shaded area
harbor optically thick disks(α3.6−8>−1.8).

YSOs in our Hectospec survey, and the (open and filled) triangles
are for the YSOs using the data from Hsu et al. (2012). The filled

Figure 33 shows the relation between the mass ac-
cretion rate, derived from the Hαand Hβline lu-
minosity, and stellar mass for the YSOs in L1641,
which is consistent with the ˙

α∼2−3 as suggested in the literature (Calvet et al. 2004;
Muzerolle et al. 2005; Mohanty et al. 2005; Natta et al.
2006; Garcia Lopez et al. 2006; Herczeg & Hillenbrand
2008; Gatti et al. 2008). A large scatter in this rela-
tion is also noted. Figure 33 also shows the ˙
Macc vs.
M∗relation for ∼20 TDs. These objects generally follow
the same trend as the normal CTTSs. Furthermore,
TDs in Fig 33(b) seems to show slightly lower accretion
rates than the normal disk populations at the same stel-

the F WHα,10% of the Hαline profiles and stellar mass. The filled
circles are for the TDs. The open circles represent the other disk
population in L1641. The sources are considered accretors when
F WHα,10% >250 km s−1, which corresponds to an accretion rate of
3.4×10−11 M⊙yr−1marked with the dotted line in the figure. For
the sources with multiple observations, the median accretion rates
are used for the plot with error bars showing their minimum and
maximum accretion rates. The YSOs are divided into four mass
bins. The thick solid lines centered on filled boxes show the median
accretion rate within these mass bins. As a comparison, the median
accretion rates for YSOs in ρOph and σOri are shown as the thick
dashed lines centered on filled diamonds, and dash-dotted lines cen-
tered on filled triangles, respectively (Rigliaco et al. 2011a). The

lar masses, which contradicts those in Fig 33(a). To un-
derstand it, we need to distinguish the better tracer for
accretion from Hαand Hβ, which is beyond the scope of
this paper.
In Fig. 34, we present another ˙
Macc vs. M∗plot for the
YSOs in L1641. The accretion rates here are estimated
from the F WHα,10% of the high-resolution Hαline pro-
files in the Hectochelle spectra. Similar to the result in
Fig. 33 and in the literature, the accretion rates generally
increase with stellar masses with a large scatter in ˙
Macc
at similar masses. We divided the YSOs into four mass
bins, and estimated the median accretion rates in each
mass bin as did in Rigliaco et al. (2011a). For compari-
son we show the median accretion rates within the same
mass bins for YSOs in ρOph and σOri (Rigliaco et al.
2011a). The L1641 region has an age between the ρOph
(<1 Myr) and σOri(∼3 Myr) regions . Within each mass
bin, the median accretion rate in ρOph is higher than
that in σOri, indicating a trend of decreasing accretion
rate with age. The YSOs in L1641 show median accre-
tion rates similar to those in ρOph within the bins for
masses >0.5 M⊙, and similar to those in σOri within
the bins with masses <0.5 M⊙, which may indicate that
accretion rate decreases faster with age in the low-mass
range than in the high-mass range.

Hartmann et al. (2006) discussed the angular momen-
tum transport in disks. The magneto-rotational insta-
bility (MRI, Balbus & Hawley 1998) is the key mech-
anism for the angular momentum transport. For the
MRI to take effect, ionization in the disks is required.
There are different sources that can ionize the gas in
disks, including cosmic rays or stellar UV and X-rays
photons impinging on the disk surface (Gammie 1996;
Glassgold et al. 1997), and thermal ionization driven by
either viscous dissipation within the disk or irradiation
of the disk surface by the central star (Hartmann et al.
2006). Hartmann et al. (2006) considered the two lim-
iting cases: (1) a lower-mass disk, in which the entire
column is ionized for an active magneto-rotational in-
stability (MRI), which is subject to full viscous evolu-
tion, resulting in α≈2.5; and (2) a higher-mass disk, in
which thermal ionization by irradiation from the central
star is dominant, causing an MRI-active surface layer
resulting in α≈1. To test this scenario, we have col-
lected a large set of YSOs with accretion rate estimates
from the literature (Gullbring et al. 1998; White & Basri
2003; Muzerolle et al. 2003; Hartigan & Kenyon 2003;
Calvet et al. 2004; Muzerolle et al. 2005; Natta et al.
2006; Mohanty et al. 2005; Garcia Lopez et al. 2006;
Herczeg & Hillenbrand 2008; Dahm 2008, Paper I),
within the star forming regions Taurus-Aurigae, IC 348,
ρOph, λOri, Orion OB, upper Scorpius, and L1641, and
L1630N. All these data are shown in Fig. 35. The de-
pendency of ˙
Macc on M⋆is steeper for the low-mass
disks around low-mass stars and brown dwarfs than for
higher mass disks around solar to intermediate mass
stars, which may support the scenario proposed by
Hartmann et al. (2006). However, Given the large scat-
ter in Fig. 35, the difference on dependency of ˙
Macc on
M⋆in different mass ranges is only marginally significant.
Furthermore, it is possible that the ages of intermediate-
mass stars are older than the sub-solar mass stars in
Fig. 35. However, There are a large uncertainty in esti-
mating ages of intermediate-mass stars from HR diagram

(Hartmann 1999), which complicates the comparison.
5.2.2. Can accretion variability explain the scattering in
˙
Macc vs. M∗?
Though the correlation between accretion rate
and stellar mass is obvious for a large sample of
young stars, individual objects with similar ages and
masses commonly scatter around the average rela-
tion by up to 2 orders of magnitude. Observa-
tions show that the amplitude of accretion variation
for CTTSs is large(Johns & Basri 1995; Gullbring et al.
1996; Alencar et al. 2001; Alencar & Batalha 2002;
Sicilia-Aguilar et al. 2010). Thus, the temporal accre-
tion variation is proposed as one potential explanation
for the large scattering in the ˙
Macc vs. M∗plot. To test
this, we have performed a multi-epoch high-resolution
spectroscopic survey of YSOs with Hectochelle covering
baselines of ∼1, 10, and ∼22 months. A total of 52 disked
YSOs were observed at two epochs separated by an inter-
val of ∼1 month, 33 YSOs were observed at two epochs
separated by ∼10 months, and 21 YSOs were observed at
two epochs separated by ∼22 months. Figure 36(a,b,c)
shows the the ratio of accretion rates ( ˙
Macc) estimated
from F WHα,10% at epochs separated by ∼1, 10, and 22
months, respectively, against their averaged F WHα,10% .
The accretion rates are estimated from F WHα,10% via
the relation between the accretion rate and FWH α,10%
from Natta et al. (2004). Figure 36(d,e,f) shows the dis-
tribution of accretion rate ratios for the accreting YSOs
(F WHα,10% >250 km/s ) which are shown in left pan-
els of Fig. 36, respectively. The Gaussian fits to these
distributions have standard deviations in the logarithm
of accretion rate ratio of ∼0.66±0.09, 0.59±0.12, and
0.35±0.06, respectively. The small standard deviation
for the 22 month interval could be due to the low num-
ber statistics. Thus, our data suggest that the accre-
tion variability cannot explain the two orders of magni-
tude scatter in accretion rates at similar masses. Our
result confirms the finding in Nguyen et al. (2009b) and
Sicilia-Aguilar et al. (2010). Nguyen et al. (2009b) have
investigated the accretion variability towards a sample of
40 young stars in Taurus and Cha I based on the Ca II
fluxes, and concluded that the intrinsic source variability
cannot be the dominating factor in the large scatter of
the ˙
Macc versus M∗relationship.
The uncertainties in calculating ˙
Macc can in-
duce a scatter of the ˙
Macc versus M∗relationship.
Herczeg & Hillenbrand (2008) discuss the possible un-
certainty contributors, including distance, stellar pa-
rameters (extinction, effective temperature, mass, and
radius), assumption of accretion geometry, conversion
from UV excess continuum emission to accretion lumi-
nosity. They concluded these uncertainties can lead to
a∼0.6 dex uncertainty in ˙
Macc for calculating ˙
Macc of
young stars in Taurus from UV excess continuum emis-
sion. When ˙
Macc is calculated from emission lines, the
uncertainties (∼0.8–1.0 dex) in ˙
Macc could be bigger than
those from UV excess emission due to large uncertain-
ties in the conversions of line quantities (line luminosi-
ties or F WHα,10% ) to accretion quantities (Lacc or ˙
Macc),
which are constructed mostly based on non-simultaneous
data (Paper I; Muzerolle et al. 1998; Natta et al. 2004;
Herczeg & Hillenbrand 2008; Rigliaco et al. 2012). The
combination of uncertainty (0.6–1.0 dex) in mea surement
and accretion variability (0.5 dex) may account for the
large scatter of the ˙
Macc versus M∗relationship.
We estimate the relative variability of F WHα,10%
(σ/ < F WHα,10% >) for the disk population with
three-epoch Hectochelle data, and plot this against stel-
lar masses in Fig. 37. As a comparison, we also
show a sample of intermediate-mass stars collected from
Mendigut´ıa et al. (2011). In the figure, the relative vari-
ability of F WHα,10% show a large scatter for stars less
than 3 M⊙, and the scatter increases with decreasing
mass. The values of σ/ < F WH α,10% >are much smaller
and show less scatter for the Herbig Be stars (M∗>3M⊙).
Mendigut´ıa et al. (2011) suggest that the distinction be-
tween σ/ < F WHα,10% >for Herbig Ae stars and Her-
big Be stars is due to the different formation mecha-
nisms of the Hαemission line. For Herbig Ae stars, Hα
line fluxes may be originate partially from the magneto-
spheric accretion flow, and thus are sensitive to accretion
variations. In Herbig Be stars Hαemission may come
from the disk surface (Vink et al. 2002; Mottram et al.
2007) and thus be less sensitive to accretion variations.
In this work, we extend the study of Mendigut´ıa et al.
(2011) to the sub-solar mass regime, and find that the
mean σ/ < F WH α,10% >in the low-mass range is larger
than that of Herbig Ae stars. This may be due to two
YSOs in L1641: Disks, Accretion, and SFH. 29

factors: (1) the accretion of sub-solar mass stars is more
variable than Herbig Ae stars or (2) accretion rate vari-
ability is independent of mass, but the Hαemission line
in Herbig Ae stars includes a contribution from a disk
wind, which is less susceptible to accretion rate fluctua-
tions, diluting the fluctuations in the Hαline.
5.2.3. How does Accretion work in disks at different
evolutionary stages?
In Fig. 38(a), we compare the Hα E W s of our TDs with
those of the YSOs with optically thick disks(α3.6−8≥
−1.8) and diskless PMS stars. The YSOs with optically
thick disks usually show strong Hαemission, while the
PMS stars without disks present weak Hαemission. The
TDs straddle this boundary with a major fraction of TDs
showing no active accretion, and a fraction of TDs show-
ing strong accretion activity. In Fig. 38(b), we show the
distribution of logarithmic ratio between the observed
Hα EW and the EW threshold for the three popula-
tions in Fig. 38(a). Here, EW threshold is the spectral
type dependent threshold used to classify the YSOs into
CTTSs or WTTSs (see Paper I). Using these EW thresh-
olds, 79±5% of YSOs with optically thick disks are clas-
sified as CTTSs while only 40±8% of TDs are CTTSs.
And 21±6% of TDs show “strong” accretion activity,
defined as having Hα EW of more than 2 times the EW
thresholds. For the YSOs with optically thick disks, this
fraction is 60±5%. Therefore, there are significantly
fewer strong accretors among TDs compared with opti-
cally thick disks. For the 6 globally depleted disks shown
in Fig. 16, only the source #16 shows an Hα EW which
is marginally above the threshold for classifying it as a
CTTS. The active accretion in source #16 is confirmed
by the Hαemission line profile (F WHα,10% ∼387 km s−1)
observed with Hectochelle (see Fig. 23). Thus, statisti-
cally only 1/6 of YSOs with globally depleted disks are
CTTSs, which is much lower than the YSOs with opti-
cally thick disks or TDs.
In Fig. 39(a) we show the F WH α,10% vs. [3.6]−[8.0]

colors for the YSOs in L1641. The diskless stars typi-
cally show small F WHα,10% with 90±9% of them show-
ing F WHα,10% <250 km s−1. The diskless stars in L1641
show a F WHα,10% distribution, peaked at ∼125 km s−1,
which is similar to that of diskless stars collected in
the literature (see Appendix A). The optically-thick disk
population have typically large F WHα,10% with a smaller
number of sources showing F WHα,10% <250 km s−1.
The TDs show a broader and flatter distribution of
F WHα,10% compared with the other two populations. If
using F WHα,10% >250 km s−1as the criterion for active
accretion, 45±12% of TDs are accretors. The fraction
of accretors increases to 77±10% among the optically-
thick disk population. The fractions of accretors for the
two populations identified with F WHα,10% are consistent
with those ( 40±8% vs. 79±5%) based on the Hα E W s.
Though the fraction of accretors among TDs is signifi-
cantly lower than that in optically-thick disk population,
the accretors in both populations show similar median
values of F WHα,10%, which are 387, and 375 km s−1, re-
spectively, thus corresponding to similar accretion rates
(Natta et al. 2004). This finding confirms our previous
result in Paper I. Sicilia-Aguilar et al. (2010) have esti-
mated the accretion rates of a sample of YSOs in the

is used to derive these distributions. In the grey filled region, the
YSOs have F WHα,10%<250 km s−1, thus considered as not accret-
ing.
Tr 37 cluster using U-band excess method, and also find
that the median accretion rates of the accreting TDs and
normal CTTSs are similar. This result is inconsistent
with what Najita et al. (2007) find in Taurus, namely
that the accretion rates of TDs are ∼10 times lower than
those of normal accreting TTS at the same disk mass.
Recently Espaillat et al. (2012) find the median accre-
tion rate of full disks is ∼4 times higher than that of ac-
creting TDs in NGC 2068 and IC 348. Thus, the relation
between accretion processes in young stars and the age
or evolutionary stage of their disks is still controversial,
and may vary in different star-forming regions.
In this work, we use the Hαline as a tracer of accretion.
The criteria that we use to classify CTTS and WTTS
may affect our results. In Fig. 39, we consider the YSOs
with F W Hα,10% <250 km s−1as WTTSs. However, some
YSOs with tiny accretion rates or with infall perpendicu-
lar to the line of sight may show F W Hα,10% <250 km s−1.
We could exclude more these YSOs among the TDs
than those among the optically-thick disks since more
than half of TDs show F W H α,10%<250 km s −1, but
only 20% of the optically-thick disk population have
F W Hα,10% <250 km s−1(see the above discussion). If
we change the criterion of F W H α,10% to 200 km s−1
for classifying CTTS and CTTS, the median values of
F W Hα,10% for accreting TDs and optically-thick disk
population are 329, and 356 km s−1, respectively. And
the corresponding accretion rate for TDs is ∼2 times
lower than that of the optically-thick disks, which can
slightly reconcile the contradiction between our results
and the others in the literature.
In Fig. 40, we combine the three distributions (the
distribution of ratios of ˙
Macc ) shown in Fig. 36(d,e,f)
together, and separate it into two distributions, one of
which is for TDs and the other for optically-thick disk
Figure 40. The distribution of ratios of ˙

tograms) and normal disk population (line-filled histograms) with

tio for the normal disk population with σ∼0.56. The dotted lines

population (α3.6−8>−1.8). We use the Gaussian func-
tion to fit the distribution in the logarithm of the ra-
tio, and derive standard deviations of ∼0.37±0.05 and
0.56±0.07, respectively, suggesting that there is no signif-
icant difference between the accretion variability of TDs
and normal disks. We have already found that the accret-
ing TDs and normal disk population show similar median
accretion rates. Here, we find their accretion variability
is also similar. Thus, we conclude that the accretion
activity of accreting TDs is similar to the normal disk
population.
5.3. Star formation modes in L1641
With the data from Spitzer, XMM, and spectroscopic
survey, we have performed a census of YSOs in L1641
(see table 2, and 3). Based on this YSO catalog, we
reexamine the issue of the star formation mode in L1641
(ie. clustered vs. isolated). We estimated the surface
density (SD) using the nearest neighbor method, which
is given with the equation density = n/(πr2
n) where rn
is the distance to the nth nearest YSO and nis set to
10. We calculate the surface density for all cataloged
YSOs (∼1390 sources) in table 2, and 3. We also cal-
culate the surface density for known YSOs in Taurus
(Luhman et al. 2010), and IC 348 (Muench et al. 2007).
Their SD distributions are shown in Fig. 41. The median
SD is 2.8, 15.7, and 177.5 pc−2in Taurus, L1641, and
IC 348, respectively. To allow a comparative study of the
SD distributions in these regions, we need to calculate the
SD for a selected sample of YSOs in each region down
to a similar completeness limit. In L1641, we only select
the YSOs with Ks<14.3 (10σlimit in the 2MASS sur-
vey), co rresponding to a 0.05 M⊙PMS star at the median
age of L1641 (Baraffe et al. 1998). We use this sample
mass limit to select the YSOs in Taurus and IC 348. We

sample in each region, 79% of the YSOs in Taurus are
located in regions with a SD less than 10 pc−2, while in
IC 348 the fraction is only 1%. In L1641, 41% of YSOs
live in regions with SD <10 pc−2. In addition, in L1641
only 6% of YSOs are in areas with SD less than 2.6 pc−2
(the median SD in Taurus), and only 5‰of YSOs are
in areas with SD larger than 141.4 pc−2(the median SD
in IC 348). The distribution of SDs in the L1641 cloud
is between that of Taurus and IC 348, confirming that
both of the two star formation modes (isolated and clus-
tered) are at work in L1641 as suggested in the literature
(Strom et al. 1993; Allen 1995, Paper I).
We estimate the SDs for Class II I, Class II, and Flat-
spectrum+Class I sources in L1641. The median SDs
are 14.7 pc−2, 17.2 pc−2, and 17.7 pc−2, for Class III,
Class II, and Flat-spectrum/C lass I sources, respectively.
In addition, 32% of Class III sources, 28% of Class II
sources, and 32% of Flat-spectrum/Class I sources are
located in regions with SDs less than 10 pc−2. Thus, our
result suggests there is no significant difference in the
SDs between the “old” Class II I sources, and “young”
Class II, or Flat-spectrum/Class I sources.
We compare the ages of “isolated” YSOs (SD≤10 pc−2)
with those of “clustered” YSOs (SD>10 pc−2) in L1641
using the sample young stars with spectral types. Both
populations show very broad age distributions with me-
dian ages of 1.6 and 1.5 Myr, respectively. A KS test
suggest that age distribution of both populations having
been drawn from a same distribution has probability of
∼0.3.
5.4. Star formation history in L1641, and the lifetime
of Flat-spectrum and Class I sources
In this work and Paper I, we have more than 800 young
stars with spectral-type estimates. For these YSOs, we
can derive their ages from the PMS evolutionary tracks,
Figure 42. The distribution of ages for the YSOs in our sample
derived using different evolutionary tracks: i.e. Dotter et al. (2008)
(D08), D’Antona & Mazzitelli (1997) (DM97), Siess et al. (2000)
(S00), and Tognelli et al. (2011) (Pisa11).
and statistically investigate the star formation history in
L1641. In Fig. 42, we show the distribution of ages for all
these YSOs estimated from four sets of PMS evolution-
ary tracks. The age distributions from D08 and DM97
suggest formation rate of stars is accelerating in L1641
starting ∼10 Myr ago. The age distributions estimated
from D08 and DM97 can be fit using the following for-
mulae:
Log N ∝κ×τ(6)
where N is the numbers of YSOs and τis the age in units
of Myr. Fitting to the YSO ages derived from the D08
and DM97 evolutionary tracks results in similar κvalues
∼ − 0.24, an indicator of the accelerating star formation
in L1641. The age distribution derived using the S00
tracks indicates that the star formation started ∼1 0 Myr
ago, and increased with time. The star formation rate
peaked 2–3 Myr a go. The age distr ibution derived using
the Pisa11 tracks display an accelerating star formation
rate starting ∼10 Myr ago, similar to those from other
PMS evolutionary tracks. However, the star formation
rate has been constant from 3 Myr ago until now. It is
still being debated whether the stellar ages from PMS
isochrone are accurate enough to constrain the star for-
mation history in star-forming regions (Palla & Stahler
2000; Hartmann 2001; Hillenbrand et al. 2008). Gen-
erally, though the age distribution varied when derived
with different evolutionary tracks, but they show some
common characteristic: in L1641 star formation was very
inactive until 5 Myr ago, and has been active for the past
∼2–3 Myr.
Observationally, the lifetimes of the Class I or Flat-
spectrum stages are statistically estimated using the ra-
tio between the number of Class I and Flat-spectrum
sources and Class II sources, assuming an age, e.g.
2±1 Myr, for Class II sources, and a star forma tion his-
tory (SFH) (Evans et al. 2009). Thus, the knowledge
of the SFH is important in estimating the lifetimes of
these sources. In the literature, the SFH of the studied
region is usually assumed to be constant (Evans et al.
2009). However, if the true star formation rate of the
studied region is accelerating, the derived lifetimes of

the Class I or Flat-sp ectrum sources would b e overesti-
mated. To demonstrate this effect, we employ a simple
model using the YSOs from L1641 and from Spitzer c2d
as examples. We use the function described in Equa-
tion 6 to characterize the SFH. Models with κ > 0 cor-
respond to a decelerating star formation rate, whereas
κ < 0 corresponds to an accelerating star formation rate
and κ= 0 represents a constant star formation rate. In
the model, we assume that Class II sources would evolve
into Class II I at an age of 3 Myr. In L1641, N(I)/N (II)
and N(Flat)/N(II) are 0.27 and 0.25, respectively, where
N(I), N(II), and N(Flat) are numbers of Class I, Class II
and Flat-spectrum sources, respectively. In the c2d sur-
vey, both fractions are ∼0.27 and ∼0.20, respectively,
for five star-forming regions, i.e. Cha II, Lupus, Serpens,
Persus, and Ophiuchus. In Fig. 43, we show how the
estimated lifetimes of Class I and Flat-spectrum sources
change with the different κvalues. If the star forma-
tion rate is assumed to be constant (κ=0), the life-
times of Class I and Flat-spectrum sources are ∼0.54
and 0.50 Myr, respectively, in L1641, and ∼0.55 and
0.41 Myr, resp ectively, for the c2d survey (Evans et al.
2009). However, if κ∼ −0.24, an accelerating star for-
mation rate, the lifetimes of both classes would decrease
by a factor of two.
6. SUMMARY
We have performed a census of YSOs in L1641 using
the data from the Spitzer imaging surveys, the XMM
surveys, and our spectroscopic surveys. We have spec-
troscopically surveyed a large sub-sample of YSOs with
Hectospec and Hectochelle. We combined the Hectospec
data with optical and infrared imaging data to estimate
the stellar effective temperatures, luminosities and ex-
tinction values of individual YSOs. The masses and ages
of individual YSOs are estimated by their placement in
the HR diagram. Accretion activity is characterized us-
ing the Hαand Hβlines. The main results in this work
are summarized as follows.
1. We presented a catalog of ∼1390 YSOs in L1641,
and constructed the SED from 0.4 to 24 µm for
each YSO. Based on the infrared SEDs, we clas-
sified the YSOs into different classes. We have
143 Class I sources, 131 Flat-spectrum sources, 533
Class II sources, and 507 Class III sources in our
YSO catalog.
2. We have used the medium-resolution spectroscopic
data from Hectospec in conjunction with the imag-
ing data to derive spectral types, line of sight ex-
tinction, estimates of the stellar mass/age, equiva-
lent widths of Hαand Hβlines, and accretion rates
from the Hαand/or Hβline luminosity for ∼300
YSOs with spectra from our observations, as well
as ∼300 YSOs with spectra types from Hsu et al.
(2012).
3. We have analyzed the high-resolution spectroscopic
data observed with Hectochelle. For 235 YSOs we
are able to examine the Hαemission line profile,
as well as look for Li I λ6708 ˚
A absorption. In our
sample, 65 YSOs have been observed at one epoch,
97 YSOs at two epochs, and 73 at three epochs,
allowing us to trace accretion variability.
4. We find one new subluminous object in our spectro-
scopic sample. It is most likely a star with a nearly
edge-on disk in which the cold outer parts of the
disk can effectively screen the central star but the
10 µm radiation of the warm inner disk can still
reach us.
5. Based on our classifications, the disk fraction in
L1641, defined as N(II)/N(II + III), is ∼50%. The
disk fraction is almost constant across the stellar
mass spectrum with a slight peak at log(M∗/M⊙)≈
−0.25.
6. We find that the ages of young stars with optically-
thick disks, transition disks and without disks in
L1641 all show very broad distributions but the
median age of diskless YSOs is larger than that of
stars with optically-thick disks. The median age of
stars with transition disks is intermediate between
these two populations.
7. Based on the infrared spectral slopes, we find that
two types of disk dissipation processes, radially de-
pleted and globally depleted evolution, are at work
in L1641.
8. The accretion rates of young stars in L1641 are con-
sistent with the ˙
Macc ∝Mα
∗relation with α∼2−3
with a large scatter in ˙
Macc for a given stellar
mass. We compiled a set of mass and accretion
rates from in this work and in the literature and
find that this data support a scenario proposed by
Hartmann et al. (2006), in which the different disk

properties around the low-mass and brown dwarf
stars, and intermediate-mass stars are responsi-
ble for the change of αbetween intermediate-mass
stars and very low-mass stars.
9. Based on the multi-epoch data from Hectochelle,
we investigated the accretion variability of young
stars in L1641 and find typical accretion rate
changes of ∼0.6 dex. We confirm that intrinsic ac-
cretion variations cannot explain the two orders
of magnitudes scatter in accretion rates for YSOs
with similar masses. We find that the relative vari-
ability of F WHα,10% for YSOs with disks in the
sub-solar mass range is larger than those in the
intermediate-mass range.
10. We confirmed 46 new transition disk objects in
L1641, 6 globally depleted disks, and provided 2
young debris disk candidates. We investigated
the accretion properties of YSOs with optically-
thick disks and transition disks based on the Hα
EW s and F WH α,10%. We find that the fraction
of accretors among transition disks (40–45%) is
significantly lower than among young stars with
optically-thick disks (77–79%). Among 6 globally
depleted disks, only one source is accreting. We
confirm our previous result that median accretion
rate of accreting transition disks is similar to that
of accreting stars with optically-thick disks. We
find that the two types of disks show similar fluc-
tuations in their accretion rate.
11. We estimated the surface densities of YSOs in
L1641 using the nearest neighbor method. We find
that there is no significant difference on the sur-
face density distributions between Cla ss III sources,
Class II source, and Flat-spectrum/Class I sources.
We compared the surface density distribution of
YSOs in L1641 with Taurus and IC348, and con-
firmed that both clustered and isolated star forma-
tion is ongoing in L1641.
12. We investigated the star formation history in L1641
based on ∼800 YSOs with spectral-type estimates.
We found that the star formation is most active
during the past 2–3 Myr. We also show that the
knowledge of star formation history is important
for constraining the lifetime of Class I and Flat-
spectrum sources.

APPENDIX
A. ACCRETION CHARACTERIZED BY F WHα,10%
White & Basri (2003) proposed to use the F WHα,10% as an alternative to distinguish accretors from non-accretors,
instead of the EW of the Hαline. They found that young stars with F WHα,10% greater than 270 km s−1are accretors.
Since a large sample of young stars with or without disks that have been observed with high-resolution Hαspectroscopy
exists in the literature, we can make statistically study how to use F WHα,10% to classify CTTSs and WTTSs.
Our basic method is described as follows. We select from the literature young stars that show no evidence for a
significant infrared excess at λ <8µm, i.e. their (inner) disks have already dissipated. The vast majority of these stars
will not be actively accreting, though the sample can contain a few TDs, some of which may still accrete. We then
plot the frequency distribution of F WH α,10% for all of these objects, and use a function to fit the distribution. We
normalize the fitted function, and use it as the probability function of F WHα,10% for non-accreting young stars.
We collected young stars from the literature covering many different star-formation regions, i.e. Orion
nebular cluster (F˝ur´esz et al. 2008; Tobin et al. 2009), NGC 2068/2071 (Flaherty & Muzerolle 2008), Tr37
(Sicilia-Aguilar et al. 2006a,b), ηCha, TW Hydrae, βPictoris, and Tucanae-Horologium groups (Sicilia-Aguilar et al.
2009; Jayawardhana et al. 2006), Cha I, and Taurus-Auriga star-forming regions (Nguyen et al. 2009a). In total, 334
stars satisfy our criteria for having no or weak infrared excess (|[3.6]−[4.5]|≤0.2, and |[5.8]−[8.0]|≤0.2). The inner
disks around these stars have been mostly cleared away and the majority of these targets should no longer be actively
accreting. In Fig. 44, we show the [5.8]−[8.0] vs. [3.6]−[4.5] color-color diagram for these targets and the fractional

enclose the region containing diskless stars. We use the F WH α,10% of these diskless stars to derive the accretion probability as a function
of F WHα,10% . The dashed lines mark the region containing Class II YSOs. (b): The distribution of F WH α,10% for diskless stars (filled

distribution of F WHα,10% . As shown in Fig 44(b), the distribution of F WH α,10% for “diskless” YSOs has a sharp
peak with a long tail towards large F WHα,10% . The long tail could be due to accreting TDs since we only use Spitzer
IRAC bands to select the “diskless” YSOs and disks with large inner holes cannot be distinguished from diskless YSOs
without data at longer wavelengths. We fit the distribution with two Gaussian functions and normalize the fitted
function to a total area of 1. The normalized function is:
Φ(F WHα,10% ) = 1.04 ×10−2exp[−(F WHα,10% −133.23
36.96 )2] + 2.20 ×10−3exp[−(F WH α,10% −223.04
82.35 )2]
We use the above function as the probability function of F WHα,10% for non-accretors. Thus, For a YSO with
an estimate of F WHα,10%, the probability that it is a non-accretor is estimated to be R∞
F WHα,10% Φ(x)dx. And the
probability that it is an accretor is prob(F WHα,10% ) = 1 −R∞
F WHα,10% Φ(x)dx. A source with F WH α,10%>25 0 km s−1,
has a probability of 90% of being an accretor. Thus we use F WHα,10% >250 km s−1as our criterion for distinguishing
accretors from non-accretors. According to this criterion, 56% of the Class II sources shown in Fig. 44 are accretors.
B. COMPARISON OF ACCRETION RATES FROM HαLINE LUMINOSITY AND F WHα,10%
In our sample young stars, there are ∼90 accreting sources which have been observed with Hectochelle. Using these
data, we estimate the accretion rates from both F WHα,10% and Hαline luminosity as described in Sect. 3.4.2. We
compare the accretion rates derived using the two methods in Fig. 45. In order to see whether there is any correlation
between both types of accretion rates, we apply a Kendall τtest. If two datasets are fully correlated, this test returns
a value of τ=1. If they are anti-correlated, we get τ=−1, and if they are independent, we obtain τ= 0. The Kendall
τtest also returns a probability p, which is smaller when the correlation is more significant. We use the Kendall τ
test to evaluate the possible correlation between the accretion rates from the two methods, which yields τ=0.3 and
p=1.5×10−5. Thus, though the scatter is large in Fig. 45, the correlation between two kinds of accretion rates is
existent. We also note that the accretion rates from F WHα,10% are systematically lower than those from Hαline
luminosity. It is beyond the scope of the current work to distinguish the better tracer for accretion and calibrate
the accretion tracer to the accretion rates. A serial of works have been done or are on-going with the data from
VLT/X-shooter (see e.g. Rigliaco et al. 2011b, 2012).
C. EVALUATING COMPLETENESS OF YSO CENSUS USING COLOR-MAGNITUDE DIAGRAM
In Fig. 46(a), we show rvs. r−icolor-magnitude diagram for ∼660 YSOs in L1641 with photometric data in
both r and i bands. Among these sources, more than 70% of them are located within a narrow band, in rvs. r−i
color-magnitude diagram. We can use the locations of the known YSOs to select the potential YSO candidates.
However the YSO candidates selected in this way could be contaminated by the reddened field stars. The fractions of
contaminators can be estimated if we know how the field stars are distributed in rvs. r−icolor-magnitude diagram.
We create ten sets of model stars in the direction of L1641 over the same area as we studied, using the Besan¸con model
of stellar population synthesis of the Galaxy(Robin et al. 2003). We derive the extinction map of the L1641 cloud

Figure 45. Comparison of accretion rates of YSOs in L1641 derived from F WHα,10% and Hαline luminosity. For the sources with

rates. The dashed line shows a 1:1 correlation, and dotted lines show a difference of 1 dex.
from the 13CO map (see Fig. 2) using the relation between the 13CO intensity and visual extinction from Paper I.
An extinction probability function is built from the extinction map of the L1641 cloud. For each model star with
the distance>500 pc, an extinction value, randomly sampled from the extinction probability function, is assigned to
it to simulate the reddening effect on the background stars from the L1641 cloud. For each set of model stars from
Besan¸con model, we sample 100 groups of extinction values from the extinction probability function. Totally, we
obtain 1000 model rvs. r−icolor-magnitude diagrams for ten sets of model stars. In Fig. 46(b), we show rvs. r−i
color-magnitude diagram for one set of model stars. The Besan¸con model predicts that the field stars contaminate our
YSO sample mostly within 1.0.r−i.1.5 and 14.0.r.17.5 in the rvs. r−icolor-magnitude diagram, which is
generally consistent with our observations (see Fig. 46(a, b)).
We visually define a region in rvs. r−icolor-magnitude diagram (enclosed by dashed lines in Fig. 46) where most of
these YSOs are located. We only study the sources with r <20 mag, considering that the completeness of the imaging
survey in rband is around 20 mag. Within our selected region, 190 sources are not included in our YSO sample.
Among them, 39 sources have been identified as field stars in Paper I and this work. With the synthetic models,
194±12 field stars are predicted to be within our defined region in rvs. r−icolor-magnitude diagram, suggesting that
our YSO census is complete till r∼20 mag.
