Identification of false positive double-lined spectroscopic binaries in LAMOST-MRS data due to moonlight contamination
Zhoulin Wang, Mikhail Kovalev, Jianping Xiong +2
We present a method for identifying false positive double-lined spectroscopic binary (SB2) candidates by analysing medium-resolution survey spectra from the Large Sky Area Multi-Ob…
A New Algol-type Binary with an Accretion disk
Tongyu He, Jiao Li, Xiaobin Zhang +10
We present a comprehensive photometric and spectroscopic analysis of the Algol-type binary \textit{Gaia} DR3 1892576067672499328. We identified the system as a spectroscopic binary…
Fundamental Parameters for Totally Eclipsing Contact Binaries Observed by TESS
Xu Ding, KaiFan Ji, ZhiMing Song +5
Totally eclipsing contact binaries provide a unique opportunity to accurately determine mass ratios through photometric methods alone, eliminating the need for spectroscopic data.…
The Initial Mass Function of the Galactic Early-type Field Stars Based on the LAMOST Survey
Qida Li, Jianping Xiong, Zhenwei Li +4
Research on the high-mass end of the initial mass function (IMF) has been limited due to a scarcity of samples. Recently, Large Sky Area Multi-Object Fiber Spectroscopic Telescope…
Orbital Parameters of 665 Double-lined Spectroscopic Binaries in the LAMOST Medium-Resolution Survey
Sufen Guo, Mikhail Kovalev, Jiao Li +9
The period, mass ratio, eccentricity, and other orbital parameters are fundamental for investigating binary star evolution. However, the number of binaries with known orbital param…
Mass, Luminosity, and Stellar Age of Early-type Stars from the LAMOST Survey
Qida Li, Jianping Xiong, Jiao Li +4
Mass () and luminosity () are fundamental parameters of stars but can only be measured indirectly. Typically, effective temperature (), surface gravity (${\rm lo…
