Description
Gravitational radiation reaction for compact binary systems has historically been studied using post-Newtonian theory, which is well adapted for the inspiraling phase and has the advantage of yielding fully analytical results. I will present recent work where we obtain the equations of motion for the two-body problem at 4.5PN order, in a generic frame. We prove for the first time the validity of the four balance equations (energy, angular momentum, linear momentum and center-of-mass position) at 2PN order, and find a novel nonlocal term when expressing the acceleration in the center-of-mass frame.
