Tate cohomology of unipotent cuspidal representations of finite groups of Lie type
Sabyasachi Dhar
Let be a prime and be an algebraic closure of the finite field with elements. Let be a connected reductive algebraic group over , and let be a…
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…
MSFA-Net: An Advanced Deep Learning Model for Identifying Blue Horizontal-Branch Stars from LAMOST DR12
Mingyuan Wang, Xiaoming Kong, Jie Ju +2
Blue horizontal-branch (BHB) stars are low-mass, core helium-burning objects with nearly constant luminosities, making them powerful tracers of old, metal-poor populations and valu…
The binary fraction of Blue Horizontal-Branch (BHB) Stars
Yanjun Guo, Kun Chen, Zhenwei Li +6
Blue horizontal-branch (BHB) stars are old, low-mass, metal-poor stars that serve as important tracers of the Galactic halo structure, kinematics, and evolution.Understanding their…
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…
The Blue Horizontal-Branch Stars From the LAMOST Survey: Atmospheric Parameters
Jie Ju, Bo Zhang, Wenyuan Cui +4
Blue horizontal-branch (BHB) stars are crucial for studying the structure of the Galactic halo. Accurate atmospheric parameters of BHB stars are essential for investigating the for…
Identification of Blue Horizontal-Branch Stars From LAMOST DR5
Jie Ju, Wenyuan Cui, Zhenyan Huo +6
We construct a new catalog of the blue horizontal-branch (BHB) stars from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) DR5 dataset, which contains 5355+81…
The Flare and Warp of the Young Stellar Disk traced with LAMOST DR5 OB-type stars
Yang Yu, Hai-Feng Wang, Wen-Yuan Cui +9
We present analysis of the spatial density structure for the outer disk from 814 \,kpc with the LAMOST DR5 13534 OB-type stars and observe similar flaring on north and south sid…
