Gravitational radiation damping in systems with compact components.
Abstract
Balance equations and the radiation reaction force are derived for slowmotion, gravitationally bound systems with compact components such as neutron stars and black holes. To obtain these results, use is made of the surface integral method developed by Einstein et al. (1938). As a consequence, all quantities involved in the derivation are finite and hence no renormalization procedure is required. Approximate expressions for the fields required to evaluate the surface integrals are obtained using the methods of matched asymptotic expansions and multiple time scales. The results obtained are the same as those derived previously for systems with noncompact components.
