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…
The Value-added Catalog of OB Stars in LAMOST DR7
Zhicun Liu, Wenyuan Cui, Jiajia Gu +4
In this work, we update the catalog of OB stars based on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) data release 7 and modified the OB stars selection c…
