Abstract:
The 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
(I0=13mag) is also reported.
