B-type stars in eclipsing binaries

M. Ratajczak, A. Pigulski and K. Pavlovski

Several aspects of stellar evolution, such as determination of masses of β Cephei-type variable stars or finding tighter constraints on the value of the convective core overshooting parameter α, can be tested with B-type stars in eclipsing binary systems. Precise photometry and high-resolution spectroscopy with high signal-to-noise ratio (SNR) are required to achieve these goals, but since many of the targets are bright enough, the challenge is an acceptable one. The approach to examine both the aforementioned aspects of stellar evolution using observations of B-type stars obtained with a wide range of spectrographs, as well as BRITE-Constellation satellites, is presented in this paper.
