Stochastic Mass Loss Rate Fluctuations and Evolution of Massive Stars
Abstract
Stochastic fluctuations were superimposed on the rate of mass loss as determined according to the radiation-pressure stellar-wind theory to evaluate the effects on the evolution of a 60-solar masses star. If the variations in the rate are of the order of those observed, there are no significant modifications of the stellar parameters, and the agreement between theory and observations cannot be improved taking into account stochastic fluctuations.
