摘要
A small moon orbiting near the edge of a ring of particles can act as a "shepherd", keeping errant ring particles from drifting away and keeping the ring boundary sharp. This phenomenon was predicted before it was observed [Goldreich & Tremaine, 1979] and has been successfully modeled by many authors, see [ Murray & Dermott, 1999]. In this paper we focus on the bifurcations that occur in the motion of a ring particle as the mass of the moon and the distance between orbits of the moon and the particle are adjusted.
