Despite their long history and astrophysical importance, some of the key properties of
neutron stars are still uncertain. The extreme conditions encountered in their interiors …

We review the current status of general relativistic studies for coalescences of black hole–
neutron star binaries. First, high-precision computations of black hole–neutron star binaries …

As gravitational-wave detectors become more sensitive and broaden their frequency
bandwidth, we will access a greater variety of signals emitted by compact binary systems …

Spin precession is one of the key physical effects that coul unveil the origin of the compact
binaries detected by ground-and space-based gravitational-wave (GW) detectors, and shed …

We investigate the causal limit of maximum mass for stars in the framework of f (R) gravity.
We choose a causal equation of state, with variable speed of sound, and with the transition …

Accurate and fast gravitational waveform (GW) models are essential to extract information
about the properties of compact binary systems that generate GWs. Building on previous …

The detection of GW170817 in gravitational waves provides unprecedented constraints on
the equation of state (EOS) of the ultradense matter within the cores of neutron stars (NSs) …

There is irresistible observational evidence that binary systems of compact objects with at
least one neutron star are progenitors of short gamma-ray bursts, as well as a production …

Seconds-long numerical-relativity simulations for black hole–neutron star mergers are
performed for the first time to obtain a self-consistent picture of the merger and post-merger …

Essentially non-oscillatory (ENO) and weighted ENO (WENO) schemes were designed for
solving hyperbolic and convection–diffusion equations with possibly discontinuous solutions …
