Abstract
We compute the variation of the Fokker-Wheeler-Feynman total linear and angular momentum of agravitationally interacting binary system under the second post-Minkowskian retarded dynamics. Theresulting OðG2Þ equations-of-motion-based, total change in the system's angular momentum is found toagree with existing computations that assumed balance with angular momentum fluxes in the radiation zone.File in questo prodotto:
