Abstract

The reaction between aperiodically growing Jeans-type gravity perturbations and stars in a rapidly rotating disk is analyzed with quasi-linear theory. The theory, applied to the solar neighborhood in the Galaxy, accounts for the observed Schwarzschild (anisotropic Maxwellian) shape for the stellar velocity ellipsoid and the increase in the random stellar velocities with age.
