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: 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…
Actinide-rich and Actinide-poor -Process Enhanced Metal-Poor Stars do not Require Separate -Process Progenitors
Erika M. Holmbeck, Anna Frebel, G. C. McLaughlin +3
The astrophysical production site of the heaviest elements in the universe remains a mystery. Incorporating heavy element signatures of metal-poor, -process enhanced stars into…
The R-Process Alliance: Spectroscopic Follow-up of Low-Metallicity Star Candidates from the Best & Brightest Survey
Vinicius M. Placco, Rafael M. Santucci, Timothy C. Beers +17
We present results from an observing campaign to identify low-metallicity stars in the Best & Brightest Survey. From medium-resolution (R ~ 1, 200 - 2, 000) spectroscopy of 857 can…
RAVE J203843.2-002333: The first highly r-process-enhanced star identified in the RAVE survey
Vinicius M. Placco, Erika M. Holmbeck, Anna Frebel +9
We report the discovery of RAVE J203843.2-002333, a bright (V = 12.73), very metal-poor ([Fe/H] = -2.91), r-process-enhanced ([Eu/Fe] = +1.64 and [Ba/Eu] = -0.81) star selected fro…
