Abstract Previous calculations, in which the luminosity is about 0.5 times the critical luminosity, are extended to higher luminosities to determine whether partial, small-scale ejections of mass continue to be the general result. The 0.2 solar-mass envelope of a 1.2 solar-mass star was perturbed by raising the interior boundary condition luminosity 10 percent to approximately the critical luminosity. After a brief period of oscillation the entire envelope was ejected. The numerical methods include time-dependent convection (not necessarily efficient) and a simplified version of a spherically extended atmosphere.
