Abstract
The first catalog of chromospherically active and ellipsoidal variable stars in the OGLE database is presented. The periods, the observed ma gnitudes and colors, their values free of interstellar extinction, and Fourier coefficients of light modulation are given for 549 stars. New color-magnitude diagrams based on new color determinations are presen ted. The chromospherically active stars are all among the bulge red gi ants, while the ellipsoidal binary stars are near the disk main sequen ce turn-off point. A discovery of a small group of very red (2 < (V - I)(0) < 6) and bright, chromospherically active bulge giants (I-0 appr oximate to 13 mag) is also reported.
