The Porous Atmosphere of η Carinae

摘要: We analyze the wind generated by great 20 yr-long super-Eddington outburst of η Carinae. show that using classical stellar atmosphere and theory, it is impossible to construct a consistent model in which sufficiently small amount mass, like one observed, shed. One expects luminosity drive thick with mass-loss rate substantially higher than observed one. The easiest way resolve inconsistency if we alleviate implicit notion atmospheres are homogeneous. An inhomogeneous, or "porous," allows more radiation escape while exerting smaller average force. Consequently, such an yields considerably lower for same total luminosity. Moreover, all applications Eddington as strict limit should be revised at least reanalyzed carefully.
