The binary fraction of Blue Horizontal-Branch (BHB) Stars
Yanjun Guo, Kun Chen, Zhenwei Li +6
Blue horizontal-branch (BHB) stars are old, low-mass, metal-poor stars that serve as important tracers of the Galactic halo structure, kinematics, and evolution.Understanding their…
The Binary Fraction of B-type Runaway Stars from LAMOST DR8
Kun Chen, Yanjun Guo, Dengkai Jiang +2
Runaway stars are defined as stars that depart from their birth clusters at high peculiar velocities. There are two main mechanisms for the formation of runaway stars, i.e., the bi…
Introduction to the Chinese Space Station Survey Telescope (CSST)
CSST Collaboration, Yan Gong, Haitao Miao +119
The Chinese Space Station Survey Telescope (CSST) is an upcoming Stage-IV sky survey telescope, distinguished by its large field of view (FoV), high image quality, and multi-band o…
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…
The new compact triple system: discovery of bright third star around contact binary using LAMOST-MRS spectra and photometry
Mikhail Kovalev, Azizbek Matekov, Sufen Guo +2
We present a study of the third star orbiting around known contact eclipsing binary J04+25 using spectra from the LAMOST medium-resolution survey (MRS) and publicly available photo…
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…
