Abstract

Gravitational radiation drives compact binaries through an inspiral phase towards a final coalescence. For binaries with spin, mass quadrupole, and magnetic dipole moments, various contributions add to this process, which is characterized by the rate of increase df/dt of the gravitational wave frequency and the accumulated number N of gravitational wave cycles. We present here all contributions to df/dt and N up to the second post-Newtonian order. Among them we give for the first time the contributions due to the self-interaction of individual spins. These are shown to be commensurable with the proper spin-spin contributions for the recently discovered J0737-3039 double pulsar and argued to represent the first corrections to the radiation reaction in the Lense-Thirring approach.
