OB stars identified in LAMOST Data Release 10
Guang Yang, Zhicun Liu, Xiao-Long Wang +2
A large sample of OB stars plays an important role in studying the stellar parameters of massive stars, as well as the formation and evolution of the Milky Way. With the help of th…
Identifying and Determining Atmospheric Parameters of BHB Stars Based on LAMOST DR11
Xiao-Long Wang, Wen-Yuan Cui, Jie Ju +4
Large catalogs of blue horizontal-branch (BHB) stars are essential for studying substructures and kinematics of the Galactic halo. And accurate determination of atmospheric paramet…
Identification of BHB stars using Synthetic SkyMapper colors from Gaia XP spectra
Guozhen Hu, Yang Huang, Wenyuan Cui +9
Blue horizontal-branch (BHB) stars are ideal tracers for mapping the structure of Galactic stellar halo. Traditionally, BHB sample stars are built from large-scale spectroscopic su…
Stellar parameters, extinction, and distances for stars in SMSS DR2 by SPar method
Mingxu Sun, Bingqiu Chen, Baokun Sun +8
The availability of large datasets containing stellar parameters, distances, and extinctions for stars in the Milky Way, particularly within the Galactic disk, is essential for adv…
Investigating lower limit of metallicity for Galactic thin disk
Guozhen Hu, Zhengyi Shao, Erbil Gugercinoglu +1
We explore the metal-poor regime of the Galactic disk on the distribution of stars in the [/M]- plane, to identify the most metal-poor thin disk (MPTnD) stars belonging to…
