Scientific paper

Rotationally-split modes can provide valuous information about the internal rotation profile of stars. This has been used for years to infer the internal rotation behavior of the Sun. The present work presents and discusses a method that may provide additional information from the mode splitting asymmetries. Using a complete second-order theory for the oscillation computations, we examine the theoretical predictions for such asymmetries for different pulsation modes: low-order g modes, mixed modes (around the fundamental radial mode), high-order p modes. The method is applied to the β Cephei star ν Eridani.
