要旨:
We discuss the Hamiltonian for the conservative dynamics of generic-orbit
arbitrary-mass-ratio spinning binary black holes, at the leading post-Newtonian
orders at each order in an expansion in spins, to all orders in the spins. The
leading-order couplings can all be obtained from a map to the motion of a test
black hole (a test body with the spin-induced multipoles of a Kerr black hole)
in the Kerr spacetime, as is confirmed with direct post-Newtonian calculations
for arbitrary mass ratios. Furthermore, all of the couplings can be "deduced"
from those of a pole-dipole test body in Kerr.
