Evolved Massive Stars at Low-metallicity V. Mass-Loss Rate of Red Supergiant Stars in the Small Magellanic Cloud
Ming Yang, Alceste Z. Bonanos, Biwei Jiang +17
We assemble the most complete and clean red supergiant (RSG) sample (2,121 targets) so far in the Small Magellanic Cloud (SMC) with 53 different bands of data to study the MLR of R…
Atmospheric parameters and kinematic information for the M giants stars from LAMOST DR9
Dan Qiu, Hao Tian, Jing Li +5
A catalog of more than 43,000 M giant stars has been selected by Li et al. from the ninth data release of LAMOST. Using the data-driven method SLAM, we obtain the stellar parameter…
LAMOST medium-resolution spectroscopic survey of binarity and exotic star (LAMOST-MRS-B): Observation strategy and target selection
Jiao Li, Jiang-Dan Li, Yan-Jun Guo +15
LAMOST-MRS-B is one of the sub-surveys of LAMOST medium-resolution (R~7500) spectroscopic survey. It aims at studying the statistical properties (e.g., binary fraction, orbital per…
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…
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…
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…
The old moving groups in the field of Taurus
Jiaming Liu, Min Fang, Hao Tian +3
In this work, we present a systematic search for stellar groups in the Taurus field by applying DBSCAN algorithm to the data from Gaia DR2. We find 22 groups, consisting of 8 young…
Stellar parametrization of LAMOST M dwarf stars
Jiadong Li, Chao Liu, Bo Zhang +3
M dwarf stars are the most common stars in the Galaxy, dominating the population of the Galaxy by numbers at faint magnitudes. Precise and accurate stellar parameters for M dwarfs…
Phase II of the LAMOST-Kepler/K2 survey. I. Time series of medium-resolution spectroscopic observations
Weikai Zong, Jian-Ning Fu, Peter De Cat +20
Phase \RNum{2} of the LAMOST-{\sl Kepler/K}2 survey (LK-MRS), initiated in 2018, aims at collecting medium-resolution spectra (; hereafter MRS) for more than s…
On the radial velocity calibrations in the LAMOST Medium-Resolution Spectroscopic Survey of Nebulae
Juan-Juan Ren, Hong Wu, Chao-Jian Wu +12
Accurate radial velocity determinations of optical emission lines (i.e. [NII]6548,6584, H, and [SII]6717,6731) are very important for investigating the kinematics and dy…
The Zwicky Transient Facility Catalog of Periodic Variable Stars
Xiaodian Chen, Shu Wang, Licai Deng +3
The number of known periodic variables has grown rapidly in recent years. Thanks to its large field of view and faint limiting magnitude, the Zwicky Transient Facility (ZTF) offers…
Radial velocity measurements from LAMOST medium-resolution spectroscopic observations: A pointing towards the Kepler field
Nian Liu, Jian-Ning Fu, Weikai Zong +20
Radial velocity is one of key measurements in understanding the fundamental properties of stars, stellar clusters and the Galaxy. A plate of stars in the Kepler field were observed…
