论文摘要
在本文中，我们考虑了鉴于光环的星系磁盘子系统的发展问题。为此，我们研究了非线性非线性磁盘在其平面上振荡的依赖性，具体取决于暗物质晕的基本参数。暗物质光环稳定了磁盘平面中的不稳定性，但破坏了其垂直振荡的稳定性。全球磁盘结构在很大程度上取决于暗物质光环的质量和形状。构建了自磨磁盘与暗物质光环的指示参数的振荡过程的进化依赖性。
In this paper, we consider the problem of the evolution of the disk subsystem of galaxies in view of the halo. To this end, we have studied the dependence of the evolution of a non-linearly non-radially disk oscillating in its plane depending on the basic parameters of the dark matter halo numerically. The dark matter halo stabilizes the instabilities in the plane of the disk, but destabilizes its vertical oscillations. The global disk structure is dependent strongly on the mass and shape of the of dark matter halo. The evolutionary dependence of the oscillation process of a self-gravitating disk versus the indicated parameters of the dark matter halo are constructed.
