Magnetic activity of several low-mass eclipsing binary

We present our new photometric and spectroscopic observations of NSVS 02500276, NSVS 07453183, NSVS 11868841, NSVS 06550671 and NSVS 10653195. The first flare-like event was detected on NSVS07453183. Using the Wilson-Devinney program, the preliminary orbital solutions and starspot parameters are der...

Zusammenfassung:We present our new photometric and spectroscopic observations of NSVS 02500276, NSVS 07453183, NSVS 11868841, NSVS 06550671 and NSVS 10653195. The first flare-like event was detected on NSVS07453183. Using the Wilson-Devinney program, the preliminary orbital solutions and starspot parameters are derived. The chromospheric activity indicators show NSVS10653195 and NSVS06550671 are active. Then, we discuss the starspot evolution on the short and long term scale. In the end, we give our future plan.
