The -Process Alliance: Fourth Data Release from the Search for -Process-Enhanced Stars in the Galactic Halo
Erika M. Holmbeck, Terese T. Hansen, Timothy C. Beers +22
This compilation is the fourth data release from the -Process Alliance (RPA) search for -process-enhanced stars, and the second release based on "snapshot" high-resolution ($…
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…
Spectroscopy of the Young Stellar Association Price-Whelan 1: Origin in the Magellanic Leading Arm and Constraints on the Milky Way Hot Halo
David L. Nidever, Adrian M. Price-Whelan, Yumi Choi +7
We report spectroscopic measurements of stars in the recently discovered young stellar association Price-Whelan 1 (PW 1), which was found in the vicinity of the Leading Arm (LA) of…
The lowest detected stellar Fe abundance: The halo star SMSS J160540.18-144323.1
T. Nordlander, M. S. Bessell, G. S. Da Costa +12
We report the discovery of SMSS J160540.18-144323.1, a new ultra-metal poor halo star discovered with the SkyMapper telescope. We measure [Fe/H] = -6.2 +- 0.2 (1D LTE), the lowest…
