Scientific paper

This study examines the stability of a family of simplified, collisionless models of galaxy collapse, to fluidlike perturbations that leave the radial density profile unaltered, but distort the galaxy's shape. The unperturbed models have constant density, and exhibit fully nonlinear oscillations around an equilibrium radius in physical space. The equations that determine the time-development of perturbations in the linear regime are derived, and are shown to be of the Mathieu type. They are solved in the special case of the quadrupole mode.
