The Equilibrium and Radial Oscillations of Cool Stellar Disks.
Abstract
Observed stars which lie in axisymmetric disks in spiral galaxies were considered. Equations used to study the radial modes of oscillation of these cool stellar disks of arbitrary structure were derived. Cool disk equilibrium was studied along with the response of a cool stellar disk to an axisymmetric potential perturbation of longer wavelength than the radial average stellar orbit. The linearized Vlasov equation and Poisson's equation were used in the later calculations.
