A simplified model of the formation of structures in dark matter
Abstract:The collapse of a rotating three-axis ellipsoid is approximated by a system of ordinary differential equations. Violent relaxation, mass and angular momentum losses are taken into account phenomenologically. The formation of the equilibrium configuration, secular instability and transition from a spheroid to a three-axis ellipsoid are investigated numerically and analytically in this dynamic model.
