Discovery of a deep, low mass ratio overcontact binary GSC 03517-00663
D. -F. Guo, K. Li, S. -M. Hu +3
When observing the blazars, we identified a new eclipsing binary GSC 03517-00663. The light curves of GSC 03517-00663 are typical EW-type light curves. Based on the observation usi…
The first photometric analysis of the near contact binary IR Cas
K. Li, S. -M. Hu, D. -F. Guo +3
The first photometric analysis of IR Cas was carried out based on the new observed BVRI light curves. The symmetric light curves and nearly flat secondary minimum indicate that ver…
