PISP: Projected-Space Inference of Stellar Parameters
Jun-Chao Liang, Yin-Bi Li, A-Li Luo +12
To improve the accuracy and efficiency of high-dimensional stellar parameter inference in large spectroscopic datasets, we propose a projection-assisted parameter-inference framewo…
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…
Systematic search for blue hyper-velocity stars from LAMOST survey
Yongkang Sun, Yang Huang, Jifeng Liu +6
Hypervelocity stars (HVSs) represent a unique class of objects capable of escaping the gravitational pull of the Milky Way due to extreme acceleration events, such as close encount…
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…
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…
Ionized gas metallicity of the strong [OIII]λ emission-line compact galaxies in the LAMOST survey
Siqi Liu, A-Li Luo, Wei Zhang +2
This article reports a sample of 1830 strong [O III] λ5007 emission-line compact galaxies discovered with the LAMOST spectroscopic survey and the photometric catalog of SDSS. We ne…
The HI gas fraction scaling relation of the Green Pea galaxies
Siqi Liu, A-Li Luo, Wei Zhang +3
Green Pea galaxies are compact galaxies with high star formation rates. However, limited samples of Green Pea galaxies have HI 21 cm measurements. Whether the HI gas fraction f_{HI…
Estimation of stellar atmospheric parameters from LAMOST DR8 low-resolution spectra with 20SNR30
Xiangru Li, Zhu Wang, Si Zeng +4
The accuracy of the estimated stellar atmospheric parameter decreases evidently with the decreasing of spectral signal-to-noise ratio (SNR) and there are a huge amount of this kind…
An Empirical Template Library for FGK and Late--type A Stars Using LAMOST Observed Spectra
Bing Du, A-Li Luo, F. Zuo +16
We present an empirical stellar spectra library created using spectra from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) DR5. This library represents a uni…
The First Data Release (DR1) of the LAMOST general survey
A. -L. Luo, Y. -H. Zhao, G. Zhao +140
The Large sky Area Multi-Object Spectroscopic Telescope (LAMOST) General Survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and…
