Constraints on model atmospheres from complex asteroseismology of the \beta Cephei stars

Solar and Stellar Astrophysics 2012-05-18 v1

Abstract

Using the method termed complex asteroseismology, we derive constraints on model atmospheres, in particular, on the NLTE effects. We fit simultaneously pulsational frequencies and the corresponding values of the nonadiabatic complex parameter f for the four \beta Cephei stars: \theta Oph, \nu Eri, \gamma Peg and 12 Lac. The LTE Kurucz models and the BSTAR2006 NLTE models are tested.
