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…
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 […
Spectroscopic Validation of Low-Metallicity Stars from RAVE
Vinicius M. Placco, Timothy C. Beers, Rafael M. Santucci +16
We present results from a medium-resolution (R ~ 2, 000) spectroscopic follow-up campaign of 1,694 bright (V < 13.5), very metal-poor star candidates from the RAdial Velocity Exper…
