Studying the hybrid pulsator 12 Lacertae: mode identification and complex seismic modelling
arXiv:1205.3798
Abstract
We present identification of the mode degree, l, for all observed frequencies of 12 Lac and results of seismic modelling which consists in fitting simultaneously the centroid mode frequencies and the corresponding values of the complex nonadiabatic f-parameter. Effects of chemical composition, opacities, core overshooting and non-LTE atmospheres were taken into account.
