Discovery of Four b Cephei Stars in Eclipsing Systems

Using the ASAS-3 photometry, we find the components of four eclipsing binary systems - V916 Cen, HD 101838, V4386 Sgr and HD 168050 - to be b Cephei-type pulsators. The first two systems are members of the young open cluster Stock 14. The pulsating stars are presumably the primary, more massive comp...

Summary:Using the ASAS-3 photometry, we find the components of four eclipsing binary systems - V916 Cen, HD 101838, V4386 Sgr and HD 168050 - to be b Cephei-type pulsators. The first two systems are members of the young open cluster Stock 14. The pulsating stars are presumably the primary, more massive components in all these systems. The components are detached and for at least two systems, V916 Cen and HD 168050, we may suspect that they will appear to be double-lined spectroscopic ones. In consequence, these stars become very attractive targets for studying pulsations in b Cephei stars by means of asteroseismology.
