| Abstract: |
A new two-dimensional (2D) non-perturbative method to compute accurate oscillation modes of rapidly rotating stars is presented.
The 2D calculations fully take into account the centrifugal distortion
of the star while the non-perturbative method includes the full influence of the Coriolis acceleration, and are used to compute oscillation modes of rapid rotators — high-order p-modes in δ Scuti stars, as well as low-order p- and g-modes in β Cephei stars.
We compare the oscillation spectra obtained for centrifugally distorted polytropes with those of Reese et al. (2006), and give the first results for a realistic 2D model of a rapidly rotating 2 M☉ evolved star computed with the method developed by Roxburgh (2006). |
