Scientific paper

In this work we present preliminary numerical results on the adiabatic frequencies in an intermediate mass star model, using a perturbation method up to the second order, taking into account radial differential rotation. We show, as we predicted, that g and mixed modes are the most affected by differential rotation. We found differences up to 5 μHz in the first and second order corrections to the frequency. This can be a very important step towards the understanding of the rotation profile in intermediate mass stars.
