The Spectroscopic and Photometric Study of a Star Cluster Sample in Andromeda Halo
Hongrui Gu, Zhou Fan, Bingqiu Chen +18
Halo star clusters serve as vital tracers for the formation and evolution of the Andromeda galaxy. In this work, we present physical parameters for 29 M31 halo star clusters, deriv…
A Tale of Two Dust Disks in Our Milky Way
Ruoyi Zhang, Haibo Yuan, Bingqiu Chen +4
Cosmic dust plays a vital role in stellar and galactic formation and evolution, but its three-dimensional structure in the Milky Way has remained unclear due to insufficient precis…
Recalibration of the Landolt UBVRI Standard Stars and the Generation of 5.4 Million New UBVRI Standard Stars using LAMOST and Gaia
Bowen Huang, Haibo Yuan, Kai Xiao +1
We present an independent validation and recalibration of the Landolt 2013 (celestial equator and ) and 2016 () standard stars in the Johnson $U…
A Comprehensive All-Sky Catalog of 3345 Molecular Clouds from Three-dimensional Dust Extinction
Tao Wang, Haibo Yuan, Bingqiu Chen +4
Understanding the distribution and properties of molecular clouds is crucial for tracing the structure and evolution of the interstellar medium and the large-scale morphology of th…
An all-sky 3D dust map Based on Gaia and LAMOST
Tao Wang, Haibo Yuan, Bingqiu Chen +6
We present a comprehensive 3D dust reddening map covering the entire Milky Way, constructed by combining reddening estimates based on LAMOST low-resolution spectra (E(BV)$_{\rm…
Additional Evidence for the Existence of a Primordial Disk System
Shuai Xu, Haibo Yuan, Bowen Huang +7
The origin of very metal-poor (VMP; [Fe/H] ) stars on planar orbits has been the subject of great attention since their first discovery. However, prior to the release of…
