Detection of the lowest mass ratio contact binary in the universe: TYC 3801-1529-1
Kai Li, Xiang Gao, Di-Fu Guo +7
This paper presents the first analysis of the contact binary TYC 3801-1529-1. We observed four sets of multiple bands complete light curves and one set of radial velocity curve of…
The First Photometric and Orbital Period Investigation of an Extremely Low Mass Ratio Contact Binary with a Sudden Period Change, TYC 4002-2628-1
Di-Fu. Guo, Kai Li, 1 Fen Liu +6
Photometric observations for the totally eclipsing binary system TYC 4002-2628-1, were obtained between November 2020 and November 2021. To determine the stellar atmospheric parame…
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.…
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 light curve modeling and orbital period change investigation of nine contact binaries around the short period cut-off
Kai Li, Chun-Hwey Kim, Qi-Qi Xia +5
In this paper, we present the first light curve synthesis and orbital period change analysis of nine contact binaries around the short period limit. It is found that all these syst…
Photometric investigations on two totally eclipsing contact binaries: V342 UMa and V509 Cam
Kai Li, Qi-Qi Xia, Jin-Zhong Liu +6
By analyzing two sets of complete light curves of V342 UMa and three sets of complete light curves of V509 Cam, we determined that the two systems are both W-…
