In the study of systems containing compact objects, like a couple of inspiraling black holes which eventually merge, important and valuable insight can be gained through approximate models of the system. We model the physical situation in which two black holes collide with orbital angular momentum by considering Robinson-Trautman spacetimes which contain purely outgoing gravitational radiation and decay to leave a Schwarzschild-like horizon. These RT spacetimes are natural candidates to study systems settling to a single black hole and also to use them as background spacetimes for a perturbation treatment.
