Prospects for Asteroseismology of Rapidly Rotating B-Type Stars

  • Chapter
Studying Stellar Rotation and Convection

Part of the book series: Lecture Notes in Physics ((LNP,volume 865))

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 m. We compare such properties with observations in rapidly rotating Be stars and discuss what is learnt from such comparisons.
