Spectroscopic and Decade-long Photometric Observations of the Contact Binary V2790 Ori: Evidence for a Brown Dwarf Companion and a Solar-like Magnetic Activity Cycle
Si-Rui Wang, Kai Li, Qi-Qi Xia +6
We present 22 sets of light curves and one radial velocity curve for the W UMa-type total eclipse contact binary system V2790 Ori, derived by combining all available public photome…
Photometric Analysis of 30 Contact Binaries in M31
Xiang Gao, Kai Li, Li-Heng Wang +3
M31, as the largest galaxy in the Local Group, is of significant importance for the study of stellar formation and evolution. Based on the data of 5,859 targets observed in M31 by…
The investigation of 84 TESS totally eclipsing contact binaries
Yani Guo, Kai Li, Liheng Wang +4
Based on the eclipsing binary catalog provided by \cite{2022ApJS..258...16P}, 84 totally eclipsing contact binaries with stable light curves were selected. The TESS light curves of…
Photometric and Spectroscopic Studies of Two Early-Type Eclipsing Binaries
Peng-Fei Ye, Kai Li, Fei Liu +2
Using high-precision photometric data from TESS, medium resolution spectroscopic data from LAMOST, and long-term eclipse timings, we provide orbital parameters for two early-type d…
Extremely Low Mass Ratio Contact Binaries. II. The First Photometric and Spectroscopic Investigations of Six Systems with Orbital Periods Longer than 0.5 days
Fei Liu, Kai Li, Xiang Gao +7
The photometric and spectroscopic studies of six contact binaries were performed for the first time. The orbital periods of all the six targets are longer than 0.5d, and we discove…
Using machine learning method for variable star classification using the TESS Sectors 1-57 data
Li-Heng Wang, Kai Li, Xiang Gao +2
The Transiting Exoplanet Survey Satellite (TESS) is a wide-field all-sky survey mission designed to detect Earth-sized exoplanets. After over four years photometric surveys, data f…
Optical Flares Detected on a Contact Binary: The First Photometric and Spectroscopic Analysis of a Long-period Low Mass Ratio Contact Binary HAT 307-0007476
Ling-Zhi Li, Kai Li, Xiang Gao +10
This paper presents the photometric and spectroscopic analysis of a long-period totally eclipsing contact binary (HAT 307-0007476) for the first time. This system is a low mass rat…
