No random Cycle-to-Cycle period changes in the β Cephei star BW Vulpeculae.

PERCY J.R., VELOCCI V. and STERKEN C.

Abstract (from CDS):

We show, using the formalism of Eddington & Plakidis, that the nonevolutionary period changes in the β Cephei star BW Vul are not the result of random cycle-to-cycle period fluctuations, as they are in several cooler types of pulsating variables. The fractional fluctuation per cycle is less than 0.002.
