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…
Investigation of projected rotational velocities of Be-type stars in LAMOST DR7
Zhicun Liu, Jiao Li, Jiaming Liu +3
Stellar rotation plays a key role in the transfer of angular momentum, and a large sample of Be-type stars with reliable projected rotational velocities is crucial for understandin…
Identification of OB associations using the LAMOST-Gaia OB star sample
Zhicun Liu, Xiao-Long Wang, Wenyuan Cui +7
OB associations, as an intermediate stage between Galactic clusters and field stars, play an important role in understanding the star formation process, early stellar evolution, an…
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…
Multiple generation star formation in Cepheus Flare
Fan Wang, Min Fang, Xiaoting Fu +8
We present an analysis of the young stellar moving group ASCC 127 using Gaia DR3 data, significantly expanding its membership to 3,971 stars -- double the number identified in prev…
