The effect of reflected and external radiation on stellar flux distributions

The effect of radiation emitted or scattered by circumsteller material, such as a stellar wind, into the stellar photosphere is investigated on the basis of a gray model atmosphere generalized to include the effects of an external radiation field and a surface boundary condition describing the refle...

Zusammenfassung:The effect of radiation emitted or scattered by circumsteller material, such as a stellar wind, into the stellar photosphere is investigated on the basis of a gray model atmosphere generalized to include the effects of an external radiation field and a surface boundary condition describing the reflection of a specified fraction, depending on the frequency, of the outgoing radiation. Substantial modifications both to the temperature and flux distributions are found.
