Linear Radial Perturbations of Supermassive Stars
Abstract
Numerical integration of the linear nonadiabatic equations for radial perturbations of physical models of supermassive stars confirm the existence of both dynamical and secular instabilities above a critical mass. The value of the latter agrees very well with that deduced from approximate stability criteria. The present analysis brings out for the first time the existence of a continuous transition between dynamical and secular modes in a sequence of models of different masses.
