We analyze the photometry of 117 OGLE stars with periodic transit events for the presence of ellipsoidal light variations, which indicate the presence of massive companions. We find that ~50% of objects may have stellar companions, mostly among the short-period systems. In our Table 1 we identify a coefficient of ellipsoidal variability for each star, ac2, which can be used to select prime candidates for planetary searches. There is a prospect of improving the analysis, and the systems with smaller ellipsoidal variability will be identified, when the correlations in the OGLE photometry are corrected for in the future, thereby providing a cleaner list of systems with possible planets.
