Periastron advance from the perturbed Binet equation
Quentin Henry
We apply the Poincaré-Lindstedt method to the perturbed Binet equation describing conservative dynamics of the perturbed Kepler problem. We show that a simple treatment of divergen…
Adiabatic tides in compact binaries on quasi-elliptic orbits: Radiation at the second-and-a-half relative post-Newtonian order

Adiabatic tides in compact binaries on quasi-elliptic orbits: Dynamics at the second-and-a-half relative post-Newtonian order
Quentin Henry, Anna Heffernan
GW200105 is the first gravitational wave detection to show signs of eccentricity, it also is a neutron star - blackhole binary. This raises the need for waveforms that incorporate…

Comparison of 4.5PN and 2SF gravitational energy fluxes from quasicircular compact binaries
Niels Warburton, Barry Wardell, David Trestini +6
Recent years have seen significant advances in models of gravitational waveforms emitted by quasicircular compact binaries in two regimes: the weak-field, post-Newtonian regime, in…
Testing regularity of black holes with X-rays and Gravitational Waves
Swarnim Shashank
Physically relevant solutions in general relativity often contain spacetime singularities, which are typically interpreted as a sign of breakdown of the theory at high densities/cu…
