We are developing a numerical method able to account for the deformation of the star by the centrifugal force and, as a first step, we determined the acoustic modes of a uniform density spheroid and studied how the spheroid flatness affects these modes.4 pages, Proceedings of "Semaine de l'Astrophysique Francaise", Edts, SF2A, EdP-Sciences Conf.
