M subdwarf research. I. Identification, modified classification system, and sample construction
Shuo Zhang, A-Li Luo, Georges Comte +7
We propose a revision of the system developed by L'epine et al. (2007) for spectroscopic M subdwarf classification. Based on an analysis of subdwarf spectra and templates from Savc…
A new Hyper-Runaway star discovered from LAMOST and GAIA: ejected almost in the galactic rotation direction
Yin-Bi Li, A-Li Luo, Gang Zhao +11
In this paper, we report the discovery of a new late-B type unbound hyper-runaway star (LAMOST-HVS4) from the LAMOST spectroscopic surveys. According to its atmospheric parameters,…
Spectral feature extraction for DB white dwarfs through machine learning applied to new discoveries in the SDSS DR12 and DR14
Xiao Kong, A-Li Luo, Xiang-Ru Li +3
Using a machine learning (ML) method, we mine DB white dwarfs (DBWDs) from the Sloan Digital Sky Survey (SDSS) Data Release (DR) 12 and DR14. The ML method consists of two parts: f…
Carbon stars identified from LAMOST DR4 using Machine Learning
Yin-Bi Li, A-Li Luo, Chang-De Du +27
In this work, we present a catalog of 2651 carbon stars from the fourth Data Release (DR4) of the Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST). Using an effici…
