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…
J-PLUS: Identification of low-metallicity stars with artificial neural networks using SPHINX
D. D. Whitten, V. M. Placco, T. C. Beers +24
We present a new methodology for the estimation of stellar atmospheric parameters from narrow- and intermediate-band photometry of the Javalambre Photometric Local Universe Survey…
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…
