On the R and Smodes in a synchronously rotating component of a binary.
Abstract
The perturbation procedure derived in a previous paper is applied to obtain the frequencies of the R and Smodes in a synchronously rotating component of a binary. It is found that a tidal action increases the rotational splitting between the frequencies of the R and Smodes. This effect is more pronounced when the central concentration of the model is low. It does not seem possible to explain the multiple periodicities of some beta CMatype stars in terms of R and Soscillations in the context of uniform rotation.
