The Southern Stellar Stream Spectroscopic Survey (S5): Chemical Abundances of Seven Stellar Streams
Alexander P. Ji, Ting S. Li, Terese T. Hansen +16
We present high-resolution Magellan/MIKE spectroscopy of 42 red giant stars in seven stellar streams confirmed by the Southern Stellar Stream Spectroscopic Survey (S5): ATLAS, Aliq…
The tidal remnant of an unusually metal-poor globular cluster
Zhen Wan, Geraint F. Lewis, Ting S. Li +18
Globular clusters are some of the oldest bound stellar structures observed in the Universe. They are ubiquitous in large galaxies and are believed to trace intense star formation e…
The Most Metal-poor Stars in the Inner Bulge
Henrique Reggiani, Kevin C. Schlaufman, Andrew R. Casey +1
The bulge is the oldest component of the Milky Way. Since numerous simulations of Milky Way formation have predicted that the oldest stars at a given metallicity are found on tight…
The R-Process Alliance: J1521-3538, a very metal-poor, extremely r-process-enhanced star with [Eu/Fe]=+2.2, and the class of r-III stars
Madelyn Cain, Anna Frebel, Alexander P. Ji +8
We report the discovery of J1521-3538, a bright (V=12.2), very metal-poor ([Fe/H]=-2.8) strongly r-process enhanced field horizontal branch star, based on a high-resolution, high s…
The R-process Alliance: First Magellan/MIKE Release from the Southern Search for R-Process-enhanced Stars
Rana Ezzeddine, Kaitlin Rasmussen, Anna Frebel +9
Extensive progress has been recently made into our understanding of heavy element production via the -process in the Universe, specifically with the first observed neutron star…
The R-Process Alliance: The Peculiar Chemical Abundance Pattern of RAVE J183013.5-455510
Vinicius M. Placco, Rafael M. Santucci, Zhen Yuan +14
We report on the spectroscopic analysis of RAVE J183013.5-455510, an extremely metal-poor star, highly enhanced in CNO, and with discernible contributions from the rapid neutron-ca…
