  A new two dimensional non-perturbative code to compute accurate oscillation
modes of rapidly rotating stars is presented. The 2D calculations fully take
into account the centrifugal distorsion of the star while the non perturbative
method includes the full influence of the Coriolis acceleration. This 2D
non-perturbative code is used to study pulsational spectra of highly distorted
evolved models of stars. 2D models of stars are obtained by a self consistent
method which distorts spherically averaged stellar models a posteriori. We are
also able to compute gravito-acoustic modes for the first time in rapidly
rotating stars. We present the dynamics of pulsation modes in such models, and
show regularities in their frequency spectra.
