Searching for TESS Photometric Variability of Possible JWST Spectrophotometric Standard Stars
Susan E. Mullally, G. C. Sloan, J. J. Hermes +7
We use data from the Transiting Exoplanet Survey Satellite (TESS) to search for, and set limits on, optical to near-infrared photometric variability of the well-vetted, candidate J…
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…
Absolute Magnitudes and Colors of RR Lyrae stars in DECam Passbands from Photometry of the Globular Cluster M5
A. Katherina Vivas, Abhijit Saha, Knut Olsen +10
We characterize the absolute magnitudes and colors of RR Lyrae stars in the globular cluster M5 in the ugriz filter system of the Dark Energy Camera (DECam). We provide empirical P…
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…
