Abstract

Using a variety of laboratory analogues and some simple models, Itry to portray the fluid dynamics of very hot stars and disks. By analogy to fluidizedbeds, we may expect the formation of photon bubbles that stir things up intoa sort of turbulence. Because of rotation, the bubbles merge tomake vortices whose presence causes inhomogeneous radiative outflowsand produces spots. These phenomena will allow the Eddington limit to be exceeded and, where the radiative outflows are locally large, mass loss will be encouraged.
