Weighing Hidden Companions of Compact Object Candidates via Rotational Broadening
Rui Wang, Zhi-Xiang Zhang, Wei-Min Gu +3
The determination of unseen companion masses () is essential for identifying compact objects in binary systems, yet obtaining reliable orbital inclinations remains one of the…
Stellar Atmospheric Parameters for Cool Dwarfs in Gaia DR3
Cai-Xia Qu, A-Li Luo, Rui Wang +4
We provide a catalogue of atmospheric parameters for 1,806,921 cool dwarfs from Gaia DR3 which lie within the range covered by LAMOST cool dwarf spectroscopic parameters: 3200 K <…
Stellar Parameters and Chemical Abundances Estimated from LAMOST-II DR8 MRS based on Cycle-StarNet
Rui Wang, A-Li Luo, Shuo Zhang +3
Deriving stellar atmospheric parameters and chemical abundances from stellar spectra is crucial for understanding the evolution of the Milky Way. By performing a fitting with MARCS…
M Subdwarf Research III. Spectroscopic Diagnostics for Breaking Parameter Degeneracy
Shuo Zhang, Hua-Wei Zhang, Georges Comte +5
To understand the parameter degeneracy of M subdwarf spectra at low resolution, we assemble a large number of spectral features in the wavelength range of 0.6-2.5 μm with band stre…
A Spectroscopic Modelling Method for the Detached Eclipsing Binaries to Derive Atmospheric Parameters
Xiang-Lei Chen, A-Li Luo, Jian-Jun Chen +5
Based on luminosity contributions, we develop a spectroscopic modelling method to derive atmospheric parameters of component stars in binary systems. The method is designed for tho…
S-type stars discovered in Medium-Resolution Spectra of LAMOST DR9
Jing Chen, A-Li Luo, Yin-Bi Li +5
In this paper, we report on 606 S-type stars identified from Data Release 9 of the LAMOST medium-resolution spectroscopic (MRS) survey, and 539 of them are reported for the first t…
