A General Model of Celestial Body Formation from Initial Condensation of Gas and Dust Particles to the “Embryos” of Planets

Abstract

This paper analyzes the main ideas of the formation of celestial bodies in accretion and protoplanetary disks. Mechanisms of the radial and orbital migration of celestial bodies are considered. According to the results of modeling, the formation of small bodies of the Solar System and the growth in their size and mass occurs at stable libration points of orbital resonances. The appearance of a single embryo in protoplanetary rings is explained by of the action of the 1/1 orbital resonance mechanism. Using a model of wave perturbations of the dust shells of protostars and a model of orbital resonance, a general model of the formation and growth of “embryos” of planets for disks with masses less than 0.1M_S was constructed.
