LAMOST-DR3 very metal-poor star catalog
We present the result of a search for very metal-poor (VMP, [Fe/H]{<}-2.0) stars in the Milky Way based on low-resolution spectra from Large sky Area Multi-Object fiber... -
Exploring the SDSS data set. I. EMP & CV stars
We present the results of a search for extremely metal-poor (EMP), carbon-enhanced metal-poor (CEMP), and cataclysmic variable (CV) stars using a new exploration tool based on... -
Very metal-poor stars with LAMOST & Subaru. I.
The chemical abundances of very metal-poor stars provide important constraints on the nucleosynthesis of the first generation of stars and early chemical evolution of the... -
Metal-poor stars observed with SALT/HRS. II.
We present results from high-resolution (R~40000) spectroscopic observations of over 200 metal-poor stars, mostly selected from the RAVE survey, using the Southern African Large... -
Dynamically tagged groups of metal-poor stars. I.
Orbital characteristics based on Gaia Early Data Release 3 astrometric parameters are analyzed for ~4000 metal-poor stars ([Fe/H]<=-0.8) compiled from the Best and Brightest... -
Metallicities of very low metal-poor stars
This work presents a first attempt to apply fuzzy cluster analysis (FCA) to analyzing stellar spectra. FCA is adopted to categorize line indices measured from LAMOST... -
Sp. follow-up of bright metal-poor stars
We present the results of spectroscopic follow-up for 1897 low-metallicity star candidates, selected from the Best and Brightest (B&B) Survey, carried out with the GMOS-N/S... -
Abundances of 22 metal-poor stars in the MW
We present high-resolution Magellan/MIKE spectra of 22 bright (9<V<13.5) metal-poor stars (-3.18<[Fe/H]{<}-1.37) in three different stellar streams, the Helmi debris... -
Stars of HETDEX. I. RVels & metal-poor stars
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is an unbiased, massively multiplexed spectroscopic survey, designed to measure the expansion history of the universe... -
The r-process Alliance; abundances in 519 stars
We derive dynamical parameters for a large sample of 446 r-process-enhanced (RPE) metal-poor stars in the halo and disk systems of the Milky Way, based on data releases from the... -
Initial vs final sample of the VMP HK/HES stars
We analyze the dynamical properties of ~1500 very metal-poor (VMP; [Fe/H]<~-2.0) halo stars, based primarily on medium-resolution spectroscopic data from the HK and... -
Metal-poor stars observed with SALT/HRS
We present the first release of a large-scale study of relatively bright (V<13.5) metal-poor stars observed with the Southern African Large Telescope (SALT), based on... -
