Scientific paper

The paper numerically examines a model of three-dimensional gravitating system of colliding particles, called 'the model of ellipsoid', in which particles are moving in the gravitational field of a central rotational ellipsoid body and interact through inelastic collisions. A program of numerical simulation of collisional evolution for this model in TQ-6 computer using BCY language is presented. The results of calculation have proved Poincare's conclusion (1911). It is shown that after very fast flattening, the system reaches a quasi-equilibrium state and successively forms a disk of finite thickness. The disk spreads slowly and a central condensation is formed.
