Interpreting CoRoT Seismic Spectra. The Effects of Rotation on Oscillations from a Perturbative Approach
Instituto de Astrofísica de Andalucía (CSIC), CP 3004, Granada, Spain
The present work is placed in the framework of the preparation for the interpretation of the seismic space data from the space mission CoRoT. In this context, rotation have become one of the most limiting factors when analysing the observed spectra of stars. A general view on the effects of rotation on the oscillations is given from the point of view of a linear perturbation analysis. As well, the latest results about the effect of shellular rotation on adiabatic oscillation frequencies are addressed. Finally, the role of rotation on asteroseismic diagnostics is discussed. In particular, échélle diagrams and analysis of rotation profile variations are examined.
