Two contact binaries with mass ratios close to the minimum mass ratio
Kai Li, Qi-Qi Xia, Chun-Hwey Kim +5
The cut-off mass ratio is under debate for contact binaries. In this paper, we present the investigation of two contact binaries with mass ratios close to the low mass ratio limit.…
The active W UMa type binary star V781 Tau revisited
Kai Li, Dongyang Gao, Shaoming Hu +3
In this paper, new determined BVR_cI_c light curves and radial velocities of V781 Tau are presented. By analyzing the light curves and radial velocities simultaneously, we found th…
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…
Discovery of a W UMa type binary GSC 03553-00845
D. -F. Guo, K. Li, S. -M. Hu +3
When observing the transiting extrasolar planets, we discovered a new W UMa type binary GSC 03553-00845. Following observation was carried out using the 1m telescope at Weihai Obse…
Optical Monitoring of OT 546 in 2009
Difu Guo, Shaoming Hu, Xu chen
We reported the monitoring results of OT 546 in V, R and I bands, observed on 22 nights from February 16 to July 1 in 2009 at Weihai Observatory of Shandong University. During our…
