Disentangling the Distant Stellar Halo Using K-Giants in the DESI Year 3 Data

Namitha Kizhuprakkat, Andrew P. Cooper, Wenting Wang +42

We present a sample of 88,959 K-giants from DESI Milky Way Survey Year 3 data, which we use to characterize the chemo-dynamical properties of the stellar halo at Galactocentric dis…

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…

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…

HR-GO II: chemical abundances of low- retrograde dynamically-tagged-groups: Revealing Thamnos as a very metal-poor substructure

Renjing Xie, Zhen Yuan, Haining Li +12

Milky Way halo substructures identified in dynamical space are known to suffer from contamination from the Milky Way in-situ stars, which makes their accreted origins uncertain. We…

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…

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…
