Gravitational waves from spinning binary black holes at the leading post-Newtonian orders at all orders in spin

摘要

We determine the binding energy, the total gravitational wave energy flux, and the gravitational wave modes for a binary of rapidly spinning black holes, working in linearized gravity and at leading orders in the orbital velocity, but to all orders in the black holes’ spins. Though the spins are treated nonperturbatively, surprisingly, the binding energy and the flux are given by simple analytical expressions which are finite (respectively third- and fifth-order) polynomials in the spins. Our final results are restricted to the important case of quasicircular orbits with the black holes’ spins aligned with the orbital angular momentum.
