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/…
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…
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…
The Origin of the Milky Way's Halo Age Distribution
Daniela Carollo, Patricia B. Tissera, Timothy C. Beers +4
We present an analysis of the radial age gradients for the stellar halos of five Milky Way mass-sized systems simulated as part of the Aquarius Project. The halos show a diversity…
