A simple model of the evolution of a dust medium

A simple model is proposed that describes the kinetics of a dust medium and reproduces some observed nonequilibrium processes that lead to the formation of planetary rings, galaxies, and large-scale fold-type structures in space. The stable formation of typical galactic structures is attributed to their relaxation to stationary dissipative attractors.Translated from Teoreticheskaya i Matematicheskaya Fizika, Vol. 103, No. 1, pp. 161–169, April, 1995.
