The rotation curve of the Milky Way measured by Classical Cepheids from Gaia DR3
Qikang Feng, Yang Huang, Huawei Zhang +1
We determine the rotation curve (RC) of the Milky Way in the range 6 < R < 18 kpc using a sample of 903 carefully selected classical Cepheids with precise proper motions and high-q…
Constraining Common Envelope Evolution in Binary Neutron Star Formation with Combined Galactic and Gravitational-Wave Observations
Zhiwei Chen, Jihui Zhang, Youjun Lu +2
Binary neutron stars (BNSs) are among the most interesting sources for multimessenger studies. A number of recently discovered BNSs in the Milky Way by radio telescopes have added…
Systematic Search for Electromagnetic Counterparts to the Binary Neutron Star Merger Candidate GW231109_235456
Zhirui Li, Zhiwei Chen, Yang Huang +2
In this letter, we present a systematic search for the electromagnetic counterparts of binary neutron star (BNS) merger candidate GW231109_235456 by examining all transients report…
A Metallicity Catalog of Very Metal-poor Main-sequence Turn-off and Red Giant Stars from LAMOST DR10
Xiangyu Li, Huiling Chen, Yang Huang +4
We present a catalog of 8,440 candidate very metal-poor (VMP; [Fe/H] < -2.0) main-sequence turn-off (MSTO) and red giant stars in the Milky Way, identified from low-resolution spec…
Systematic search for blue hyper-velocity stars from LAMOST survey
Yongkang Sun, Yang Huang, Jifeng Liu +6
Hypervelocity stars (HVSs) represent a unique class of objects capable of escaping the gravitational pull of the Milky Way due to extreme acceleration events, such as close encount…
The Mini-SiTian Array: Imaging Processing Pipeline
Kai Xiao, Zhirui Li, Yang Huang +19
As a pathfinder of the SiTian project, the Mini-SiTian (MST) array, employed three commercial CMOS cameras, represents a next-generation, cost-effective optical time-domain survey…
