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 first photometric and spectroscopic analysis of the extremely low mass ratio contact binary NSVS 5029961
Shu-Yue Zheng, Kai Li, Qi-Qi Xia
We performed photometric and spectroscopic investigations of NSVS 5029961 for the first time. The new BV(RI)-band light curves were obtained with the 1.0-m telescope at Weihai…
Photometric study and absolute parameters estimation of six totally eclipsing contact binaries
Kai Li, Qi-Qi Xia, Chun-Hwey Kim +6
High precision CCD observations of six totally eclipsing contact binaries were presented and analyzed. It is found that only one target is an A-type contact binary (V429 Cam), whil…
The first photometric investigation and spectroscopic analysis of two contact binaries: ASAS J124343+1531.7 and LINEAR 2323566
Qiqi Xia, Raul Michel, Kai Li +1
The multi-color passband CCD light curves of ASAS J124343+1531.7 and LINEAR 2323566 were first obtained by the 0.84-m Ritchey-Chrétien telescope with follow up observations by the…
