First results of the Central-East-South European Binary Star Study Group (CESEB),al smaller telescopes located at various places in the CESE region. Preliminary results, based on a pilot study started in 2001, about radial velocity and light curve variations of the active WUMa system LS Del are presented here.

Spot Modelling of , Andromedae,rs (temperature, size, location) are variable in time. We present spot modelling results for six two-colour light curves which show that spots preferably appear on the stellar surface towards the companion star and opposite to it, where the distortion also causes dimming. Therefore, simple fitting o

The Near-Contact System V387 Cygni: BVRI Photometry and Modelling,atory, Greece. Their analysis with the W-D program indicates a semidetached configuration with possible cool spots, although no O’ Connell effect is present and a strong asymmetry after . can be explained assuming either a strong flare or circumstellar matter.

Monitoring Secular Orbital Period Variations of Some Eclipsing Binaries at the Ankara University Ob at the Ankara University Observatory. Among the systems of our observing list are CK Boo, V502 Oph and V836 Cyg that show long-term secular variations in their orbital periods. We use classical O-C diagram analysis technique as a tool to reveal the character of the period variations of these binary
