A Numerical Study of a Gravitating System of Colliding Particles: Applications to the Dynamics of Saturn's Rings and to the Formation of the Solar System
Abstract
We consider numerically a threedimensional system of particles moving in the gravitational field of a central mass point and interacting through inelastic collisions. After a very fast flattering, the system reaches a quasiequilibrium state in which there are still collisions and the rings tend to a finite thickness of a few times the mean size of the particles.
