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…
The Origins of Neutron-capture Elements In Globular Cluster M22
Muhammad Zeshan Ashraf, Wenyuan Cui, Hongjie Li
The chemical abundances of metal-poor stars in globular clusters provide important constraints on their evolutionary scenarios. Using both main r-process and weak r-process pattern…
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…
Revisiting the Li abundances of Stars with and without Detected Planets from the High Resolution Spectroscopy
Jinxiao Qin, Hong-Liang Yan, Wenyuan Cui +12
Whether the presence of planets affects the lithium (Li) abundance of their host stars is still an open question. To investigate the difference of the Li abundance between planet-h…
The Mini-SiTian Array: A Pathfinder for the SiTian Project
Yang Huang, Jifeng Liu, Hong Wu +5
The Mini-SiTian Array serves as a pathfinder for the SiTian project, which aims to survey the entire sky in bands every 30 minutes, reaching a limiting magnitude of 21. This…
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…
