Locate a stellar flare from the M dwarf LAMOST J1332+5057
Guang-Wei Li, Gui-Ping Zhou, Bing Du +2
Young M-type stars exhibit frequent flares, which would seriously impact their habitable planets. Since stellar surfaces cannot be resolved, flare locations remain unknown. Here, b…
A comprehensive catalogue of OB cluster candidates in M31 and their association with giant molecular clouds
Yuan Liang, Guang-Wei Li, Chao-Wei Tsai +1
We present a new catalogue of 578 OB cluster (OBC) candidates in the Andromeda galaxy (M31), identified using a MeanShift-based algorithm on HST's F275W-band imaging from the PHAT…
Chemical abundances of seven stars in the GD-1 stream
Jing-Kun Zhao, Guang-Wei Li, Wako Aoki +13
We present the first detailed chemical abundances for seven GD-1 stream stars from Subaru/HDS spectroscopy. Atmospheric parameters were derived via color calibrations (…
A photometric and spectroscopic study of eight semi-detached eclipsing binaries
Yajuan Lei, Guiping Zhou, Liang Wang +3
By cross-matching the eclipsing binary catalog from TESS with that from LAMOST MRS, semi-detached eclipsing binaries with radial velocities coverage spanning more than 0.3 phases w…
The white-light superflares from cool stars in GWAC triggers
Guang-Wei Li, Liang Wang, Hai-Long Yuan +16
M-type stars are the ones that flare most frequently, but how big their maximum flare energy can reach is still unknown. We present 163 flares from 162 individual M2 through L1-typ…
Discovery of Two Different Full Disk Evolutionary Patterns of M-type T Tauri Stars with LAMOST DR8
Hasitieer Haerken, Guang-Wei Li, Min Li +2
The full disk, full of gas and dust, determines the upper limit of planet masses, and its lifetime is critical for planet formation, especially for giant planets. In this work, we…
The preliminary statistical analysis of LAMOST DR8 low resolution AFGK stars
Yan hui Chen, Guang Wei Li, Hong Shu
We download the LAMOST DR8 low resolution catalog 6,478,063 AFGK tpye stars and plot the figures of effective temperature, gravitational acceleration, and metal abundance. Some sma…
Galactic O-type stars in LAMOST data
Guang-Wei Li
This paper reports 209 O-type stars found with LAMOST. All 135 new O-type stars discovered so far with LAMOST so far are given. Among them, 94 stars are firstly presented in this s…
LAMOST J040643.69+542347.8: the fastest Rotator in the Galaxy
Guang-Wei Li
Rotation and binary interaction play important roles in understanding the nature of massive stars (>8 Msun). Some interesting transients, such as the long-duration gamma-ray bursts…
Irregular changes in Hα emission line of V423 Aur observed by LAMOST Medium-Resolution Spectrographs
Chao-Jian Wu, Hong Wu, Chih-Hao Hsia +8
We obtained 7 spectra of the Be star V423 Aur on Dec. 5th, 2017 using the LAMOST Medium-Resolution Spectrograph with exposures from 600 to 1200 seconds. These spectra show the irre…
Sky Subtraction for LAMOST
Zhong-Rui Bai, Hao-Tong Zhang, Hai-Long Yuan +7
Sky subtraction is the key technique in data reduction of multi-fiber spectra. Knowledge of the related instrument character is necessary to determine the method adopted in sky sub…
Candidate members of the Pal 5, GD-1, Cetus Polar, and Orphan tidal stellar halo streams from Sdss DR9, Lamost DR3 and APOGEE catalogues
Guang-Wei Li, Brian Yanny, Hao-Tong Zhang +8
We present candidate members of the Pal 5, GD-1, Cetus Polar, and Orphan tidal stellar streams found in LAMOST DR3, SDSS DR9 and APOGEE catalogs. In LAMOST DR3, we find 20, 4, 24 h…
LAMOST Spectroscopic Survey of the Galactic Anticentre (LSS-GAC): the second release of value-added catalogues
Maosheng Xiang, Xiaowei Liu, Haibo Yuan +29
We present the second release of value-added catalogues of the LAMOST Spectroscopic Survey of the Galactic Anticentre (LSS-GAC DR2). The catalogues present values of radial velocit…
Validation of LAMOST Stellar Parameters with the PASTEL Catalog
Hua Gao, Huawei Zhang, Maosheng Xiang +8
Recently the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) published its first data release (DR1), which is ranked as the largest stellar spectra dataset in th…
The stellar kinematics in the solar neighborhood from LAMOST data
Hai-Jun Tian, Chao Liu, Jeffrey L. Carlin +6
We use about 200,000 FGK type main-sequence stars from the LAMOST DR1 data to map the local stellar kinematics. With the velocity de-projection technique, we are able to derive the…
