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…

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…

The Metallicity Gradient and Complex Formation History of the Outermost Halo of the Milky Way

Sarah E. Dietz, Jinmi Yoon, Timothy C. Beers +1

We present an examination of the metallicity distribution function of the outermost stellar halo of the Galaxy based on an analysis of both local (within 4 kpc of the Sun, ~16,500…

Galactic Archeology with the AEGIS Survey: The Evolution of Carbon and Iron in the Galactic Halo

Jinmi Yoon, Timothy C. Beers, Sarah Dietz +6

Understanding the evolution of carbon and iron in the Milky Way's halo is of importance because these two elements play crucial roles constraining star formation, Galactic assembly…
