Prospects for asteroseismology of rapidly rotating B-type stars
Abstract
In rapidly rotating stars Coriolis forces and centrifugal deformations modify the properties of oscillations; the Coriolis force is important for low-frequency modes, while the centrifugal deformation affects mainly p-modes. Here, we discuss properties of g- and r-mode oscillations in rotating stars. Predicted frequency spectra of high-order g-modes (and r-modes) excited in rapidly rotating stars show frequency groupings associated with azimuthal order . We compare such properties with observations in rapidly rotating Be stars, and discuss what is learnt from such comparisons.
