Validity of the Traditional Approximation for Gamma Doradus pulsators
Francois Lignieres (IRAP), Jérôme Ballot (IRAP)
Recent asteroseismic analysis of g modes in Gamma Doradus stars have been conducted in the framework of the Traditional Approximation. Using the TOP code, we investigate the range of validity and the accuracy of this approximation for a typical Gamma Doradus stellar model. The presence of convective layers is expected to play an important role that was not taken into account in our previous investigation (Ballot et al. 2012). The influence of the full treatment of the Coriolis effects on the period spacing will be emphasized.
