NONLINEAR NONRADIAL OSCILLATIONS SELF- GRAVITATING DISK WITH ACCOUNTING HALO
Abstract
In this paper, we consider the problem of the evolution of the disk subsystem of galaxies,
taking into account the halo. To do this, we studied the dependence of the evolution of a non-linear non-
radially oscillating disk in its plane on the main parameters of the dark matter halo numerically. The dark
matter halo stabilizes instabilities in the disk plane but destabilizes its vertical oscillations. The structure
of the global disk strongly depends on the mass and shape of the dark matter halo. Evolutionary
dependences of the process of oscillations of a self-gravitating disk on the indicated parameters of the
dark matter halo are constructed
