What can we learn from observations of early-type binary stars with a pulsating component?
Several recent studies have successfully probed stellar interiors of pulsating variable stars by means of helio- and asteroseismology. Stellar physical parameters that may be obtained from dynamical studies of such variables that furthermore are components in binaries or multiple systems, may for the first time provide strong tests of the current understanding of stellar structure and evolution for massive stars. The principles behind such orbital and pulsational studies will briefly be described, illustrated with a few examples. The first results from an ongoing study of a unique case among the beta Cephei stars on the Southern Sky, the pulsating component in the eclipsing binary system HD92024, are described.
