Thermal instability in the wind of Wolf-Rayet stars
Published online by Cambridge University Press: 25 May 2016
Abstract
In this study, we investigate the formation of clumps at the base of the wind of early-type stars via thermal instability in the presence of Alfvén wave heating. As a result we show the existence of two stable equilibrium regions, one at high temperature, the diffuse medium, and another at low temperature, the clumps. We show that the two stable equilibrium regions can coexist over a narrow range of pressures describing the diffuse medium and the clumps.
