Abstract: The new photometric space-borne survey missions CoRoT and Kepler will be ableto detect minute flux variations in binary stars due to relativistic beamingcaused by the line-of-sight motion of their components. In all but very shortperiod binaries P>10d, these variations will dominate over the ellipsoidaland reflection periodic variability. Thus, CoRoT and Kepler will discover a newobservational class: photometric beaming binary stars. We examine this newcategory and the information that the photometric variations can provide. Thevariations that result from the observatory heliocentric velocity can be usedto extract some spectral information even for single stars.
