cds-question@unistra.frvariable-starsphotometryThe first catalog of chromospherically active and ellipsoidal variable stars in the OGLE database is presented. The periods, the observed magnitudes 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 presented. The chromospherically active stars are all among the bulge red giants, while the ellipsoidal binary stars are near the disk main sequence 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_=13mag) is also reported.1996AcA....46..389Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/46/389CatalogResearchIsServedByTAP VizieR generic servicerelated-toI/244 : OGLE General Catalog of Stars.
