The Spectroscopic Binaries from LAMOST Medium-Resolution Survey (MRS). I. Searching for Double-lined Spectroscopic Binaries (SB2s) with Convolutional Neural Network
Bo Zhang, Ying-Jie Jing, Fan Yang +13
We developed a convolutional neural network (CNN) model to distinguish the double-lined spectroscopic binaries (SB2s) from others based on single exposure medium-resolution spectra…
The Early-type Stars from LAMOST survey: Atmospheric parameters
YanJun Guo, Bo Zhang, Chao Liu +7
Massive stars play key roles in many astrophysical processes. Deriving atmospheric parameters of massive stars is important to understand their physical properties and thus are key…
LAMOST Time-Domain Survey: First Results of four 2 plates
Song Wang, Haotong Zhang, Zhongrui Bai +23
From Oct. 2019 to Apr. 2020, LAMOST performs a time-domain spectroscopic survey of four 2 plates with both low- and med-resolution observations. The low-resolution spectroscopic…
The Binarity of Early-type Stars from LAMOST Medium-resolution Spectroscopic Survey
Yanjun Guo, Jiao Li, Jianping Xiong +8
Massive binaries play significant roles in many fields. Identification of massive stars, particularly massive binaries, is of great importance. In this paper, by adopting the techn…
Binary fraction of O and B-type stars from LAMOST data
Feng Luo, Yong-Heng Zhao, Jiao Li +2
Binary stars plays important role in the evolution of stellar populations . The intrinsic binary fraction () of O and B-type (OB) stars in LAMOST DR5 was investigated in t…
The Relative Calibration of Radial Velocity for LAMOST Medium Resolution Stellar Spectra
Jianping Xiong, Bo Zhang, Chao Liu +3
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) started median-resolution spectroscopic (MRS, R7500) survey since October 2018. The main scientific goa…
Self-consistent Stellar Radial Velocities from LAMOST Medium-Resolution Survey (MRS) DR7
Bo Zhang, Jiao Li, Fan Yang +12
Radial velocity (RV) is among the most fundamental physical quantities obtainable from stellar spectra and is rather important in the analysis of time-domain phenomena. The LAMOST…
