Abstract

We study how moderate rotation affects photometric observables inβ Cephei stars. The most important effect is the rotationalmode coupling of modes with harmonic degree, ℓ, differing by2 and the same azimuthal order, m, if the frequencies are close.This is not an uncommon situation among unstable modes in βCep stars. Positions of the coupled modes in the amplitude ratiovs. phase difference diagrams are aspect, i, – andm-dependent. Inference from the diagrams becomes morecomplicated.
