Authors: Jing Zeng, Clifford M. Will (Washington University, St. Louis) Date: 20 Apr 2007 Abstract: We study gravitational radiation reaction in the equations of motion for binary systems with spin-orbit coupling, at order (v/c)ˆ7 beyond Newtonian gravity, or O(v/c)ˆ2 beyond the leading radiation reaction effects for non-spinning bodies. We use expressions for the energy and angular momentum flux at infinity that include spin-orbit corrections, together with an assumption of energy and angular momentum balance, to derive equations of motion that are valid for general orbits and for a class of coordinate gauges. We show that the equations of motion are compatible with those derived earlier by a direct calculation. |
