Gravitational radiation reaction for compact binary systems at the fourth-and-a-half post-Newtonian order in harmonic coordinates

Luc Blanchet, Guillaume Faye, Emeric Seraille +1

We derive the gravitational radiation-reaction (RR) force in the harmonic coordinate system at the fourth-and-a-half post-Newtonian (4.5PN) order in the case of compact binary syst…

Waveform Modelling for the Laser Interferometer Space Antenna

LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144

LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…

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…

Gyroscopic Gravitational Memory from quasi-circular binary systems

Guillaume Faye, Ali Seraj

Gravitational waves cause freely falling spinning objects to precess, resulting in a net orientation change called gyroscopic memory. In this paper, we will consider isolated gravi…

Gravitational radiation reaction for compact binary systems at the fourth-and-a-half post-Newtonian order

Luc Blanchet, Guillaume Faye, David Trestini

We compute the gravitational radiation-reaction force on a compact binary source at the fourth-and-a-half post-Newtonian (4.5PN) order of general relativity, i.e., 2PN order beyond…
