The R-Process Alliance: Chemical Abundances for a Trio of R-Process-Enhanced Stars -- One Strong, One Moderate, One Mild
Madelyn Cain, Anna Frebel, Maude Gull +9
We present detailed chemical abundances of three new bright (V ~ 11), extremely metal-poor ([Fe/H] ~ -3.0), r-process-enhanced halo red giants based on high-resolution, high-S/N Ma…

The R-Process Alliance: Discovery of the first metal-poor star with a combined r- and s-process element signature
Maude Gull, Anna Frebel, Madelyn G. Cain +11
We present a high-resolution (R~35,000), high signal-to-noise (S/N>200) Magellan/MIKE spectrum of the star RAVE J094921.8-161722, a bright (V=11.3) metal-poor red giant star with […
