Stability of the Stellar Disks of Flat Galaxies. II. The Effect of Spatial Inhomogeneity
Abstract
The investigation of the first paper of the present series is extended to include the effect of spatial inhomogeneity, i.e., the surface density, angular velocity, and velocity dispersion gradients of a stellar disk. Similar to the investigation of the first paper, the well- elaborated mathematical methods of plasma kinetic theory are used. The influence of disk inhomogeneity on the oscillation spectrum of different small-amplitude oscillations in a stellar disk of flat galaxies is studied.
