Identify main-sequence binaries from the Chinese Space Station Telescope Survey with machine learning

Jia-jia Li, Jin-liang Wang, Kai-fan Ji +4

The statistical properties of double main sequence (MS) binaries are very important for binary evolution and binary population synthesis. To obtain these properties, we need to ide…

The First Photometric Analysis of Two Low Mass Ratio Contact Binary Systems In TESS Survey

Qiyuan Cheng, Jianping XIong, Xu Ding +8

Low mass-ratio (q) contact binary systems are progenitors of stellar mergers such as blue straggles (BS) or fast-rotating FK Com stars. In this study, we present the first light cu…

Calibration of metallicity of LAMOST M dwarf stars Using FGK+M wide binaries

Dan Qiu, Jiadong Li, Bo Zhang +3

Estimating precise metallicity of M dwarfs is a well-known difficult problem due to their complex spectra. In this work, we empirically calibrate the metallicity using wide binarie…
