Nonresonant mode coupling in double-mode pulsators

Abstract

The simplest model for the evolution to steady nonlinear stellar pulsation is nonresonant interaction involving two linearly unstable modes. One scenario models a double-mode pulsator, while another one shows evolution to classic pulsators. In all cases exact shock-like solutions have been obtained.
