Mass distribution for single-lined hot subdwarf stars in LAMOST
Zhenxin Lei, Ruijie He, Peter Nemeth +4
Masses for 664 single-lined hot subdwarf stars identified in LAMOST were calculated by comparing synthetic fluxes from spectral energy distribution (SED) with observed fluxes from…
Se-ResNet+SVM model: an effective method of searching for hot subdwarfs from LAMOST
Cheng Zhongding, Kong xiaoming, Wu Tianmin +5
In this paper, we apply the feature-integration idea to fuse the abstract features extracted by Se-ResNet with experience features into hybrid features and input the hybrid feature…
Hot subdwarf stars identified in LAMOST DR8 with single-lined and composite spectra
Zhenxin Lei, Ruijie He, Peter Nemeth +6
222 hot subdwarf stars were identified with LAMOST DR8 spectra, among which 131 stars show composite spectra and have been decomposed, while 91 stars present single-lined spectra.…
Hot subdwarf stars identified in Gaia DR2 with spectra of LAMOST DR6 and DR7 I. Single-lined spectra
Zhenxin Lei, Jingkun Zhao, Péter Németh +1
182 single-lined hot subdwarf stars are identified by using spectra from the sixth and seventh data release (DR6 and DR7) of the Large Sky Area Multi-Object Fibre Spectroscopic Tel…
Searching for Hot Subdwarf Stars in LAMOST DR1-II. Pure spectroscopic identification method for hot subdwarfs
Zhenxin Lei, Yude Bu, Jingkun Zhao +2
Employing a new machine learning method, named hierarchical extreme learning machine (HELM) algorithm, we identified 56 hot subdwarf stars in the first data release (DR1) of the La…
New hot subdwarf stars identified in Gaia DR2 with LAMOST DR5 spectra -- II
Zhenxin Lei, Jingkun Zhao, Péter Németh +1
388 hot subdwarf stars have been identified by using the Hertzsprung-Russell (HR) diagram built from the second data release (DR2) of the Gaia mission. By analyzing their observed…
