Abstract
Using post-Newtonian equations of motion for fluid bodies that include radiation-reaction terms at 2.5 and 3.5 post-Newtonian (PN) order ( and beyond Newtonian order), we derive the equations of motion for binary systems with spinning bodies. In particular we determine the effects of radiation reaction coupled to spin-orbit effects on the two-body equations of motion, and on the evolution of the spins. For a suitable definition of spin, we reproduce the standard equations of motion and spin-precession at the first post-Newtonian order. At 3.5 PN order, we determine the spin-orbit induced reaction effects on the orbital motion, but we find that radiation damping has no effect on either the magnitude or the direction of the spins. Using the equations of motion, we find that the loss of total energy and total angular momentum induced by spin-orbit effects precisely balances the radiative flux of those quantities calculated by Kidder et al. The equations of motion may be useful for evolving inspiraling orbits of compact spinning binaries.

In discussions of inspiralling compact binaries, one often sees the statement that spin-orbit terms are 1.5 PN order. This is because, for such system, one treats the radius as being of order , and the rotational velocity as being of order unity (especially for rapidly rotating black holes); consequently, the spin-orbit term in this case is effectively of order . Because the equations derived in this paper apply to arbitrary systems treatable with PN methods, we will stick with the formal PN ordering of spin terms.
