We describe the evolution of slowly spinning compact objects in the late inspiral with Newtonian corrections due to spin, tides, dissipation and post-Newtonian corrections to the point mass term in the action within the effective field theory framework. We evolve the system numerically using a simple algorithm for point particle simulations and extract the lowest-order Newtonian gravitational waveform to study its phase evolution due to the different effects. We show that the matching of coefficients of the effective field theory for compact objects from systems that the gravitational wave observatories LIGO-Virgo currently detects might be possible and it can place tight constraints on fundamental physics.
We introduce a rigorous and general framework to study systematically self-gravitating elastic materials within general relativity, and apply it to investigate the existence and viability, including radial stability, of spherically symmetric elastic
We produce the first astrophysically-relevant numerical binary black hole gravitational waveform in a higher-curvature theory of gravity beyond general relativity. We simulate a system with parameters consistent with GW150914, the first LIGO detectio
We study how a strong gravity affects the equation of state of matters. For this purpose, we employ a canonical ensemble of classical monoatomic ideal gas inside a box in a Rindler spacetime. The total energy decreases monotonically with the increase
Tidal effects have an important impact on the late inspiral of compact binary systems containing neutron stars. Most current models of tidal deformations of neutron stars assume that the tidal bulge is directly related to the tidal field generated by
We present SphericalNR, a new framework for the publicly available Einstein Toolkit that numerically solves the Einstein field equations coupled to the equations of general relativistic magnetohydrodynamics (GRMHD) in a 3+1 split of spacetime in sphe
