Abstract:

The quasi-stationary method for black hole binary inspiral is an approximation for studying strong-field effects while suppressing radiation reaction. In this paper we use a nonlinear scalar field toy model to: (a) explain the underlying method of approximating binary motion by periodic orbits with radiation; (b) show how the fields in such a model are found by the solution of a boundary value problem; (c) demonstrate how a good approximation to the outgoing radiation can be found by finding fields with a balance of ingoing and outgoing radiation (a generalization of standing waves).
