The evolution of selfgravitating clusters of gasdust nebulae participating in planetary body accumulation
Abstract
A mathematical model for the evolution of selfgravitating gasdust clusters is presented. A method of twoscale expansion to a set of hydrodynamic and thermodynamic equations describing the behavior of the selfgravitating gasdust clusters is used. The dependence of the pressure and temperature distribution functions on the mass and characteristic density values and the typical course of cluster evolution is analyzed.
