Abstract

One fundamental problem of the physics of planetary rings is to find the mechanical characteristics of a typical particle. It is impossible to understand either the origin of the rings or the dynamics of the collective processes without a detailed study of the properties of the particles. In the present section we shall therefore study the physics of collisions between rigid bodies which are the simplest and most popular model of the particles in the planetary rings. Collisions between rigid bodies are, however, interesting also for many other fields of astrophysics; they are an important evolutionary springboard for modern cosmogonical models. The formation of the planets and satellites started with collisions and the coalescence of solid particles (Safronov 1969, Safronov and Vityazev 1983). The surface structure of the large bodies in the solar system is in many respects caused by meteoritic impacts.
