A -like metallicity profile in the disk of the Sagittarius dwarf galaxy
Zixi Guo, Xiang-Xiang Xue, Jiang Chang +12
Unveiling the properties of the progenitors that formed the tidal structures of the Milky Way (MW) is essential for exploring the MW's assembly history. Such studies further afford…
Testing Chemical Tagging with LAMOST: Intrinsic Abundance Dispersion of Subgiant Stars in the Galactic Disk
Wu Yaqian, Xiang Maosheng, Zhao Gang +4
The scatter in elemental abundances among stars of similar age and metallicity reflects chemical inhomogeneity in their birth environments, making abundance scatter a key observabl…
Multiple populations detection with the Chinese Space Station Survey Telescope main survey camera
Zhuohang Li, Xia Li, Hao Tian +6
Multiple stellar populations (MPs), characterized by star-to-star light-element abundance variations, are ubiquitous in globular clusters (GCs). Spectroscopy directly reveals these…
The multiple corrugations in the Galactic disk derived from the LAMOST and Gaia survey data
Jifei Wang, Zhuohan Li, Chengdong Li +6
Large spectroscopic and astrometric surveys have revealed complex wave-like features in the Milky Way disk, suggesting that its kinematic and chemical structures are shaped by time…
The Rotating Bulge and Halo in the Milky Way: Evidence of Angular Momentum Transferred from the Decelerating Bar
Zhuohan Li, Chengdong Li, Gang Zhao +2
Recent observations indicate that both the Milky Way bulge and inner halo exhibit angular momentum, although the origin and evolution of this prograde signature remain ambiguous. O…
An Actinide-boost Star Discovered in the Gaia-Sausage-Enceladus
Yangming Lin, Haining Li, Ruizheng Jiang +6
We report the discovery of an actinide-boost, very metal-poor (), -process-enhanced () star, LAMOST J0804+5…
Mapping the Milky Way with Gaia Bp/Rp spectra I: Systematic flux corrections and atmospheric parameters for 68 million stars
Xianhao Ye, Wenbo Wu, Carlos Allende Prieto +8
Gaia Bp/Rp spectra for over two hundred million stars have great potential for mapping metallicity across the Milky Way. We aim to construct an alternative catalog of atmospheric p…
Hierarchical Absorption in LAMOST low Resolution Normalized Spectra
Yu-Fu Shen, Zhuohan Li
According to the hierarchical clustering scenario, galaxies like the Milky Way form hierarchically, and many supporting evidences have been found in the Galactic halo. However, mos…
Exploring the ex-situ components within Gaia DR3
Zhuohan Li, Gang Zhao, Ruizhi Zhang +3
The presence of Gaia DR3 provides a large sample of stars with complete 6D information, offering a fertile ground for the exploration of stellar objects that were accreted to the M…
