Abstract
Frequency spectra of unstable modes for typical models of β Cephei, SPB and S Scuti variables are presented. Comparison of theoretical and observed instability ranges allows to constrain possible parameters of the stellar models. As an example, models of θ 2 Tau are considered. The main uncertainties in the determination of the theoretical frequency ranges for δ Sct variables are due to unsatisfactory treatment of convection. The structure of rotationally split multiplets for the low-order modes excited in δ Sct stars is discussed. The rotational coupling between close modes of spherical harmonic degree, ϱ,differing by 2, can significantly disturb the frequency spectrum.
