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…
Spot and Facula Activity Variations of the Eccentric Detached Eclipsing Binary KIC 8098300 Based on the Time-series Orbital Solutions
Hubiao Niu, Jianning Fu, Jiaxin Wang +1
The LAMOST spectra and light curves are combined to investigate the detached eclipsing binary KIC 8098300, which shows the O'Connell effect caused by spot/facula modu…
LTD064402+245919: A Subgiant with a 1-3 M Undetected Companion Identified from LAMOST-TD Data
Fan Yang, Bo Zhang, Richard J. Long +11
Single-line spectroscopic binaries recently contribute to the stellar-mass black hole discovery, independently of the X-ray transient method. We report the identification of a sing…
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…
Double-, triple-line spectroscopic candidates in the LAMOST Medium-Resolution Spectroscopic Survey
Chun-qian Li, Jian-rong Shi, Hong-liang Yan +3
The LAMOST Medium-Resolution Spectroscopic Survey (LAMOST-MRS) provides an unprecedented opportunity for detecting multi-line spectroscopic systems. Based on the method of Cross-Co…
Discovery of multiple p-mode pulsation frequencies in the roAp star, HD 86181
Fangfei Shi, Donald W. Kurtz, Daniel L. Holdsworth +5
We report the frequency analysis of a known roAp star, HD 86181 (TIC 469246567), with new inferences from TESS data. We derive the rotation frequency to be = 0.48753 $\pm…
A triplet of the only pulsation mode detected in the DAV star G132-12
Wen-Chao Su, Jian-Ning Fu, Jian-Xing Chen +5
Hydrogen atmosphere pulsating white dwarfs, also known as DAV stars, are the most abundant type of pulsating white dwarfs. High-temperature DAV stars exhibit in general a small num…
Asteroseismology of RRab variable star EZ Cnc from K2 photometry and LAMOST spectroscopy
Jiangtao Wang, Jianning Fu, Weikai Zong +2
EZ Cnc, or EPIC 212182292, is a non-Blazhko RRab variable star located in the field of K2 Campaign 16. Its atmospheric parameters (, , [M/H]) and radial veloc…
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…
