A 3D Chemodynamical Census of Inner-Galaxy Metal-poor Giants to [Fe/H]~-3.5
Shenglan Sun, Yang Huang, Fangzhou Jiang +8
The earliest assembly of the Milky Way remains poorly understood, yet the spatial, chemical, and kinematic properties of its most metal-poor stars provide a unique fossil record of…
Chasing the formation history of the Galactic metal-poor disc
Xiaokun Hou, Ruizhi Zhang, Haining Li +1
In our previous work, we identified metal-poor stars ([Fe/H] -1.0) from the LAMOST Survey. This work estimates their chemical abundances and explores the origin a…
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…
Main-sequence Turnoff Stars as Probes of the Ancient Galactic Relic: Chemo-dynamical Analysis of a Pilot Sample
Renjing Xie, Haining Li, Ruizhi Zhang +5
The main-sequence turnoff (MSTO) stars well preserve the chemical properties where they were born, making them ideal tracers for studying the stellar population. We perform a detai…
The Shape and Mass of the Galactic Dark Matter Halo from the Axisymmetric Jeans Model
Lan Zhang, Xiang-Xiang Xue, Ling Zhu +8
We explore the density profile, shape, and virial mass of the Milky Way's dark matter halo using K giants (KG) from LAMOST and SDSS/SEGUE, as well as blue horizontal branch (BHB) s…
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…
