✦ Synopsis

We use the impulse approximation to derive analytical formulae for the escape probability from a simple binary system that interacts with a third body. The binary system is made up of a massless body in circular orbit around a massive object, and we assume that the two massive bodies follow a Schuster (or Plummet) distribution. Within the ranges imposed by the impulsive approximation to the parameters of the encounter, we find good agreement between our results and those obtained from numerical experiments.
