Higher-order-in-spin interaction Hamiltonians for binary black holes from source terms of Kerr geometry in approximate ADM coordinates

arXiv:0712.1515 · doi:10.1103/PhysRevD.77.104001

Abstract

The Kerr metric outside the ergosphere is transformed into ADM coordinates up to the orders and , respectively in radial coordinate and reduced angular momentum variable , starting from the Kerr solution in quasi-isotropic as well as harmonic coordinates. The distributional source terms for the approximate solution are calculated. To leading order in linear momenta, higher-order-in-spin interaction Hamiltonians for black-hole binaries are derived.
