Candidate Members of the VMP/EMP Disk System of the Galaxy from the SkyMapper and SAGES Surveys
Jihye Hong, Timothy C. Beers, Young Sun Lee +15
Photometric stellar surveys now cover a large fraction of the sky, probe to fainter magnitudes than large-scale spectroscopic surveys, and are relatively free from the target-selec…
Probing the Galactic Halo with RR Lyrae Stars -- V. Chemistry, Kinematics, and Dynamically Tagged Groups
Jonathan Cabrera Garcia, Timothy C. Beers, Yang Huang +9
We employ a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric-metallicity and distance estimates from the newly calibrated ------[Fe/H] and …
Chemo-Dynamically Tagged Groups of CEMP Stars in the Halo of the Milky Way. I. Untangling the Origins of CEMP- and CEMP-no Stars
Joseph Zepeda, Timothy C. Beers, Vinicius M. Placco +7
We construct a sample of 644 carbon-enhanced metal-poor (CEMP) stars with abundance analyses based on moderate- to high-resolution spectroscopic studies. Dynamical parameters for t…
The R-Process Alliance: Chemo-Dynamically Tagged Groups II. An Extended Sample of Halo -Process-Enhanced Stars
Derek Shank, Timothy C. Beers, Vinicius M. Placco +8
Orbital characteristics based on Gaia Early Data Release 3 astrometric parameters are analyzed for -process-enhanced (RPE; [Eu/Fe] ) metal-poor stars ([Fe/…
Origin of highly -process-enhanced stars in a cosmological zoom-in simulation of a Milky Way-like galaxy
Yutaka Hirai, Timothy C. Beers, Masashi Chiba +5
The -process-enhanced (RPE) stars provide fossil records of the assembly history of the Milky Way and the nucleosynthesis of the heaviest elements. Observations by the -Proce…
Dynamically Tagged Groups of Metal-Poor Stars II. The Radial Velocity Experiment Data Release 6
Derek Shank, Dante Komater, Timothy C. Beers +2
Orbital characteristics based on Gaia Early Data Release 3 astrometric parameters are analyzed for metal-poor stars ([Fe/H] ) compiled from the RAdial Vel…
Dynamically Tagged Groups of Metal-Poor Stars from the Best \& Brightest Survey
Derek Shank, Timothy C. Beers, Vinicius M. Placco +9
Orbital characteristics based on Gaia Early Data Release 3 astrometric parameters are analyzed for metal-poor stars ([Fe/H] ) compiled from the Best B…
Beyond spectroscopy. I. Metallicities, distances, and age estimates for over twenty million stars from SMSS DR2 and Gaia EDR3
Yang Huang, Timothy C. Beers, Christian Wolf +8
Accurate determinations of stellar parameters and distances for large complete samples of stars are keys for conducting detailed studies of the formation and evolution of our Galax…
Targeting Bright Metal-poor Stars in the Disk and Halo Systems of the Galaxy
Guilherme Limberg, Rafael M. Santucci, Silvia Rossi +7
We present the results of spectroscopic follow-up for 1897 low-metallicity star candidates, selected from the Best & Brightest (B&B) Survey, carried out with the GMOS-N/S (Gemini N…
The R-Process Alliance: Chemo-Dynamically Tagged Groups of Halo -Process-Enhanced Stars Reveal a Shared Chemical-Evolution History
Dmitrii Gudin, Derek Shank, Timothy C. Beers +11
We derive dynamical parameters for a large sample of 446 -process-enhanced (RPE) metal-poor stars in the halo and disk systems of the Milky Way, based on data releases from the…
