Theoretical light curves are computed for a binary system consisting of a massive early type main sequence star and a compact supernova remnant, in order to examine the possibility of detecting compact companions to OB-runaway stars. Computations are made in the 5 color Walraven filter system, using the Roche equipotential model. The influence of the period, and inclination is examined and an analysis is made of the chance of finding such systems. Results show that a number of systems (notably HD 108 and HD 53975) may have measurable variations.
