1: Spacetime modes excitation in odd-parity = 2 waves from stars models of Tab. 4.1 and a Schwarzschild black hole of the same mass 1.4M. Dependence of the ring-down phase on the width b of the initial Gaussian pulse: for b = 2 the process of excitation of the space-time modes shows the same qualitative features for the black hole and for the stars.

Questa tesi si inserisce nel campo di ricerca della relativita' numerica che consiste nella soluzione numerica delle equazioni di Einstein (equazioni di campo per la metrica accoppiate alle equazioni per la materia) al fine di simulare sorgenti astrofisiche in forte campo gravitazionale (es. buchi neri, stelle di neutroni, sistemi binari). Le princ...

Binary neutron stars (BNS) and neutron star-black hole (NSBH) binaries are one of the most promising gravitational wave (GW) sources to probe matter effects. Upcoming observing runs of LIGO-Virgo-KAGRA detectors and future third generation detectors like Einstein Telescope and Cosmic Explorer will allow the extraction of detailed information on the...

A numerical-relativity calculation yields in general a solution of the Einstein equations including also a radiative part, which is in practice computed in a region of finite extent. Since gravitational radiation is properly defined only at null infinity and in an appropriate coordinate system, the accurate estimation of the emitted gravitational w...
The late part of the gravitational wave signal of binary neutron star inspirals can in principle yield crucial information on the nuclear equation of state via its dependence on relativistic tidal parameters. In the hope of analytically describing the gravitational wave phasing during the late inspiral (essentially up to contact) we propose an exte...
