Abstract

The evolution of one-dimensional two-phase-space-density selfgravitating systems of stars is investigated by following the motion of the boundary curves of the systems in phase space. A qualitative agreement with Lynden-Bell's theory predicting, for the most probably state, velocity dispersions inversely proportional to the phase space density of the component at the star formation, is found.
