Highly eccentric inspirals into a black hole
Thomas Osburn, Niels Warburton, Charles R. Evans
We model the inspiral of a compact stellar-mass object into a massive nonrotating black hole including all dissipative and conservative first-order-in-the-mass-ratio effects on the…
Particle on the Innermost Stable Circular Orbit of a Rapidly Spinning Black Hole
Samuel E. Gralla, Achilleas P. Porfyriadis, Niels Warburton
We compute the radiation emitted by a particle on the innermost stable circular orbit of a rapidly spinning black hole both (a) analytically, working to leading order in the deviat…
Octupolar invariants for compact binaries on quasi-circular orbits
Patrick Nolan, Chris Kavanagh, Sam R Dolan +3
We extend the gravitational self-force methodology to identify and compute new tidal invariants for a compact body of mass on a quasi-circular orbit about a black hole o…
Applying the effective-source approach to frequency-domain self-force calculations: Lorenz-gauge gravitational perturbations
Barry Wardell, Niels Warburton
With a view to developing a formalism that will be applicable at second perturbative order, we devise a new practical scheme for computing the gravitational self-force experienced…
Comparison Between Self-Force and Post-Newtonian Dynamics: Beyond Circular Orbits
Sarp Akcay, Alexandre Le Tiec, Leor Barack +2
The gravitational self-force (GSF) and post-Newtonian (PN) schemes are complementary approximation methods for modelling the dynamics of compact binary systems. Comparison of their…
