Scattering and bound observables for spinning particles in Kerr spacetime with generic spin orientations
We derive the radial action of a spinning probe particle in Kerr spacetime from the worldline
formalism in the first-order form, focusing on linear in spin effects. We then develop a novel …

Post-adiabatic waveform-generation framework for asymmetric precessing binaries
J Mathews, A Pound - arXiv preprint arXiv:2501.01413, 2025 - arxiv.org
Recent years have seen rapid progress in calculations of gravitational waveforms from
asymmetric compact binaries containing spinning secondaries. Here we outline a complete …

Flux-balance laws for spinning bodies under the gravitational self-force
AM Grant - arXiv preprint arXiv:2406.10343, 2024 - arxiv.org
The motion of an extended, but still weakly gravitating body in general relativity can often be
determined by a set of conserved quantities. If they are sufficient in number, this allows for a …
