Abstract The oblique pulsator model by Kurtz was generalized to account for the observed properties of rapidly oscillating Ap stars. In this model, which includes advection and an oblique magnetic field, the modes are represented, in general, by a superposition of all spherical harmonics having the appropriate degree, l. It is predicted that an observer will report a mode splitting into (2l + 1)-frequency components with the spacing equal to the rotation frequency of the star. The relative amplitudes at these frequencies are predicted following from a postulated selective excitation mechanism due to the field, and the diagnostic potential of the data on these Ap stars is discussed.
