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 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…
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…
LAMOST Spectroscopic Survey of the Galactic Anti-centre (LSS-GAC): target selection and the first release of value-added catalogues
Haibo Yuan, Xiaowei Liu, Zhiying Huo +16
As a major component of the LAMOST Galactic surveys, the LAMOST Spectroscopic Survey of the Galactic Anti-centre (LSS-GAC) aims to survey a significant volume of the Galactic thin/…
