On the issue of the model of formation of planet systems of the solar-type stars

M. S. Legkostupov

Keldysh Institute of Applied Mathematics RAS

Abstract: In this paper for the first time there is presented in full the model of protoplanetary rings — the model of formation of planetary systems of solar-type stars, which is based on the origin and development of large-scale gravitational instabilities (protoplanetary gas-dust rings) in protoplanetary disks of stars. The results of a comparison of the main theories and models of the formation of planetary systems of solar-type stars with the data of astrophysical observations of protoplanetary disks are presented. It is shown that the data of astrophysical observations confirm the validity of the model of protoplanetary rings. In the model of protoplanetary rings, the theoretical forеcast is given for astrophysical observations of the evolution of structures of gas-dust rings of a number of protoplanetary disks of stars. Suggestions are formulated for further development of numerical algorithms for the evolution of protoplanetary disks of solar-type stars, including all stages of evolution, as well as the formation of protoplanets.

Keywords: astrophysical observations, protosolar nebula, collapse, protoplanetary disk, gravitational instability, protoplanetary ring, planetary system.
