Chemical abundances of seven stars in the GD-1 stream
Jing-Kun Zhao, Guang-Wei Li, Wako Aoki +13
We present the first detailed chemical abundances for seven GD-1 stream stars from Subaru/HDS spectroscopy. Atmospheric parameters were derived via color calibrations (…
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…
A Modified Initial Mass Function of the First Stars with Explodability Theory under Different Enrichment Scenarios
Ruizheng Jiang, Gang Zhao, Haining Li +1
The most metal-poor stars record the earliest metal enrichment triggered by Population III stars. By comparing observed abundance patterns with theoretical yields of metal-free sta…
High-α-Metal-Rich stars in the LAMOST-MRS survey and its connection with the galactic bulge
Haopeng Zhang, Yuqin Chen, Gang Zhao +6
We report the detection of a large sample of high--metal-rich stars on the low giant branch with dex in the LAMOST-MRS survey. This special group corresponds to a…
Dynamical Relics of the Ancient Galactic Halo
Zhen Yuan, G. C. Myeong, Timothy C. Beers +11
We search for dynamical substructures in the LAMOST DR3 very metal-poor (VMP) star catalog. After cross-matching with Gaia DR2, there are 3300 VMP stars with available high-quality…
Metal-poor Stars Observed with the Automated Planet Finder Telescope. II. Chemodynamical Analysis of Six Low-Metallicity Stars in the Halo System of the Milky Way
Mohammad K. Mardini, Vinicius M. Placco, Ali Taani +2
In this work, we study the chemical compositions and kinematic properties of six metal-poor stars with [Fe/H] in the Galactic halo. From high-resolution (R ~110,000)…
