Abstract
Exploiting simple yet remarkable properties of relativistic gravitational
scattering, we use first-order self-force (linear-in-mass-ratio) results to
obtain arbitrary-mass-ratio results for the complete third-subleading
post-Newtonian (4.5PN) corrections to the spin-orbit sector of spinning-binary
conservative dynamics, for generic (bound or unbound) orbits and spin
orientations. We thereby improve important ingredients of models of
gravitational waves from spinning binaries, and we demonstrate the improvement
in accuracy by comparing against aligned-spin numerical simulations of binary
black holes.
