The Phenomenological Classification of TESS Eclipsing Binaries
Shi-Qi Liu, Kai Li, Xiao-Dian Chen +1
Eclipsing binaries are crucial astrophysical laboratories for studying stellar parameters and evolutionary processes. In this study, we constructed a machine-learning-based model f…
Physical Parameters of 146 Contact Binaries Derived from Light and Radial Velocity Curves
Kai Li, Xiang Gao, Si-Rui Wang +1
We present a comprehensive analysis of 146 contact binaries using medium-resolution LAMOST spectra and photometric data from the All-Sky Automated Survey for SuperNovae (ASAS-SN) a…
A Photometric and Spectroscopic investigation of 11 TESS eclipsing contact binaries
Yani Guo, Kai Li, Yanke Tang +4
By cross-matching the eclipsing binary catalog provided by Prsa et al. (2022) with LAMOST medium resolution spectra, we obtained 11 targets. Combining light and radial velocity cur…
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…
A neural network model for quickly solving multiple-band light curves of contact binaries
Kai Li, Li-Heng Wang, Xiang Gao
The advent of large-scale photometric surveys has led to the discovery of over a million contact binary systems. Conventional light curve analysis methods are no longer adequate fo…
BSN-II: The First Light Curve Study of Eight Total Eclipsing Contact Binary Stars with Shallow Fillout Factors
Atila Poro, Kai Li, Raul Michel +6
This study provides the first comprehensive analysis of eight total-eclipse W Ursae Majoris-type contact binary systems. Ground-based photometric multiband observations were conduc…
