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…
A Helium-shell Burning Blue Horizontal Branch Star Produced from Common Envelope Evolution
Jiao Li, Changqing Luo, Hai-Liang Chen +16
Observationally, blue horizontal branch (BHB) stars are defined as hot stars occupying a characteristic region between the extreme blue horizontal branch and RR Lyrae variables in…
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 origin of B-type runaway stars based on kinematics
Yanjun Guo, Chao Liu, ZhiCun Liu +5
Runaway stars depart their birthplaces with high peculiar velocities. Two mechanisms are commonly invoked to explain their origin, the binary supernova scenario (BSS) and the dynam…
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…
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…
The measurement of masses of OB-type stars from LAMOST DR5
Zhenyan Huo, Zhicun Liu, Wenyuan Cui +5
The measurements of masses and luminosities of massive stars play an important role in understanding the formation and evolution of their host galaxies. In this work, we present th…
A Robust Hot Subdwarfs Identification Method Based on Deep Learning
Lei Tan, Ying Mei, Zhicun Liu +5
Hot subdwarf star is a particular type of star that is crucial for studying binary evolution and atmospheric diffusion processes. In recent years, identifying Hot subdwarfs by mach…
The Early-type Stars from LAMOST survey: Atmospheric parameters
YanJun Guo, Bo Zhang, Chao Liu +7
Massive stars play key roles in many astrophysical processes. Deriving atmospheric parameters of massive stars is important to understand their physical properties and thus are key…
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…
A Catalogue of OB Stars from LAMOST Spectroscopic Survey
Zhicun Liu, Wenyuan Cui, Chao Liu +3
We present 22\,901 OB spectra of 16\,032 stars identified from LAMOST DR5 dataset. A larger sample of OB candidates are firstly selected from the distributions in the spectral line…
