Compact objects occupy a pivotal role in the exploration of Nature. The interest spans from
the role of compact objects in astrophysics to their detection through various methods …

The nuclear symmetry energy characterizes the variation of the binding energy as the
neutron to proton ratio of a nuclear system is varied. This is one of the most important …

Understanding the link between massive (≳ 30 M⊙) stellar black holes (BHs) and their
progenitor stars is a crucial step to interpret observations of gravitational-wave events. In this …

Determining the Equation of State (EOS) of dense neutron-rich nuclear matter is a shared
goal of both nuclear physics and astrophysics. Except possible phase transitions, the density …

We review the formation and evolution of compact binary stars consisting of white dwarfs
(WDs), neutron stars (NSs), and black holes (BHs). Mergings of compact-star binaries are …

Rotating relativistic stars have been studied extensively in recent years, both theoretically
and observationally, because of the information they might yield about the equation of state …

One of the primary science goals of the next generation of hard x-ray timing instruments is to
determine the equation of state of matter at supranuclear densities inside neutron stars by …

This review describes the events leading up to the discovery of the Kerr metric in 1963 and
the enormous impact the discovery has had in the subsequent 50 years. The review …

With the remarkable success of the Ligo-Virgo-Kagra consortium in detecting binary black
hole mergers, it has become possible to use the population properties to constrain our …

A subfraction of dark matter or new particles trapped inside celestial objects can significantly
alter their macroscopic properties. We investigate the new physics imprint on celestial …
