In this study, we investigate the fundamental astrophysical parameters of the old open cluster NGC 188 through two complementary methods: isochron-fitting and spectral energy distribution (SED) analysis. Using photometric, astrometric, and spectroscopic data from the Gaia Data Release 3 (DR3, Gaia Collaboration et al. 2023), we identify 868 most li...
Bu çalışmada, astronomi ve astrofizik bilim alanında araştırmalar yürütülen "Türkiye" adresli kurumların 1980-2020 yılları arasındaki yayın performanslarının analizleri sunulmaktadır. "Türkiye" adresli araştırmacıların bilim atıf indeksi kapsamındaki dergilerde yayınladıkları, Web of Science veri tabanındaki bilimsel makaleler incelenmiştir. Analiz...
Bu çalışmada, Güneş civarından seçilmiş metalce fakir yıldızların tayfsal enerji dağılımları (SED) analiz edilmiş ve teorik olarak hesaplanan model atmosfer fitleriyle, yıldızların tayfsal analizlerinde kullanılabilecek öncül temel astrofizik parametreler tayin edilmiştir. Bu amaç doğrultusunda Polarbase veri tabanı ve ELODIE tayf kütüphanesinden m...
We present photometric, astrometric, and kinematic studies of the old open star clusters NGC 1193 and NGC 1798. Both of the clusters are investigated by combining data sets from Gaia Early Data Release 3 (EDR3) and CCD UBV observational data. E(B − V ) color excesses are derived for NGC 1193 as 0.150 ± 0.037 and for NGC 1798 as 0.505 ± 0.100 mag th...
We present photometric, astrometric, and kinematic studies of the old open star clusters NGC 1193 and NGC 1798. Both of the clusters are investigated by combining data sets from Gaia EDR3 and CCD UBV observational data. Analysis of the radial distribution of stars through the cluster regions indicates that the cluster limit radii are $r_{\rm lim}=8...
In this first study, which is aimed to regularly examine the annual publication performances of the Turkish institutions conducting research in the fields of astronomy and astrophysics. The time frame of 2020 was selected for this investigation and 135 scientific articles published by researchers from Turkey in journals included in Science Citation...
