| Popis | Recent calculations of multicomponent radiatively driven stellar winds of cool B stars showed that friction between individual components significantly lowers the terminal wind velocity. In addition, there is a large heating at the base of these winds caused by frictional and Gayley-Owocki heating. Such winds may be highly unstable resulting either in radiative-acoustic waves propagating both downstream and upstream or in unstable regions. Consequently, instabilities in the stellar wind influence the photospheric structure of these stars. |
