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 βCephei stars: θOph, νEri, γPeg and 12 Lac. The LTE Kurucz models and the BSTAR2006 NLTE models are tested.
