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…
Two Populations of Carbon-Enhanced Metal-Poor Stars in the Disk System of the Milky Way
Sarah E. Dietz, Jinmi Yoon, Timothy C. Beers +2
We present a chemo-dynamical analysis of low-resolution () spectroscopy of stars from the AAOmega Evolution of Galactic Structure (AEGIS) survey, focusing on two key p…
Dynamically Tagged Groups of Very Metal-poor Halo Stars from the HK and Hamburg/ESO Surveys
Guilherme Limberg, Silvia Rossi, Timothy C. Beers +13
We analyze the dynamical properties of 1500 very metal-poor (VMP; [Fe/H] ) halo stars, based primarily on medium-resolution spectroscopic data from the HK and…
Metal-Poor Stars Observed with the Southern African Large Telescope
Kaitlin C. Rasmussen, Joseph Zepeda, Timothy C. Beers +5
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 high-resolu…
Discovery of a large population of Nitrogen-Enhanced stars in the Magellanic Clouds
José G. Fernández-Trincado, Timothy C. Beers, Dante Minniti +7
We report the APOGEE-2S discovery of a unique collection of nitrogen-enhanced mildly metal-poor giant stars, peaking at [Fe/H] with no carbon enrichment, toward the…
The enigmatic globular cluster UKS~1 obscured by the bulge: \textit{H}-band discovery of nitrogen-enhanced stars
José G. Fernández-Trincado, Dante Minniti, Timothy C. Beers +13
The presence of nitrogen-enriched stars in globular clusters provides key evidence for multiple stellar populations (MPs), as has been demonstrated with globular cluster spectrosco…
