Constants of motion in gravitational self-force theory

David Trestini, Zachary Nasipak, Adam Pound

Synergies between self-force theory and other approaches to the gravitational two-body problem have traditionally relied on calculations of gauge-invariant observables as functions…

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…

Constants of motion and fundamental frequencies for elliptic orbits at fourth post-Newtonian order

David Trestini

In the case of nonspinning compact binary systems on quasi-elliptic orbits, I obtain the conservative map between the constants of motion (energy and angular momentum) and the fund…

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…

Quasi-Keplerian parametrization for compact binaries on hyperbolic orbits in scalar-tensor theories at second post-Newtonian order

Davide Usseglio, David Trestini, Abhishek Chowdhuri

We obtain the generalized quasi-Keplerian parametrization for compact binaries on quasihyperbolic orbits at second post-Newtonian (2PN) order in a class of massless scalar-tensor t…

Schott term in the binding energy for compact binaries on circular orbits at fourth post-Newtonian order

David Trestini

The phasing for compact binary systems on circular orbits was obtained in arXiv:2304.11185 at fourth-and-a-half post-Newtonian (4.5PN) order thanks to two main ingredients: the 4PN…
