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…
Scalable Stellar Parameter Inference Using Python-based LASP: From CPU Optimization to GPU Acceleration
Jun-Chao Liang, Yin-Bi Li, A-Li Luo +13
To enhance the efficiency, scalability, and cross-survey applicability of stellar parameter inference in large spectroscopic datasets, we present a modular, parallelized Python fra…
Estimating Stellar Atmospheric Parameters and [α/Fe] for LAMOST O-M type Stars Using a Spectral Emulator
Jun-chao Liang, A-Li Luo, Yin-Bi Li +7
In this paper, we developed a spectral emulator based on the Mapping Nearby Galaxies at Apache Point Observatory Stellar Library (MaStar) and a grouping optimization strategy to es…
An Empirical Sample of Spectra of M-type Stars with Homogeneous Atmospheric-Parameter Labels
Bing Du, A-Li Luo, Song Wang +6
The discrepancies between theoretical and observed spectra, and the systematic differences between various spectroscopic parameter estimates, complicate the determination of atmosp…
Stellar cycle and evolution of polar spots in an M+WD binary
Xinlin Zhao, Song Wang, Xue Li +4
Stellar activity cycles reveal continuous relaxation and induction of magnetic fields. The activity cycle is typically traced through the observation of cyclic variations in total…
Projected rotational velocities for LAMOST stars with effective temperature lower than 9000 K
Fang Zuo, A-Li Luo, Bing Du +5
In Data Release 9 of LAMOST, we present measurements of v sin i for a total of 121,698 stars measured using the Medium Resolution Spectrograph (MRS) and 80,108 stars using the Low…
