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…
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…
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…
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 $Gaia…
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/…
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…
