S-PLUS: Beyond Spectroscopy IV. Stellar Parameters and Elemental-abundance Ratios for Six Million Stars from DR4 and First Results for the Magellanic Clouds
Yang Huang, Timothy C. Beers, Kai Xiao +18
We combine narrow/medium-band filter photometry from the Southern Photometric Local Universe Survey (S-PLUS) DR4 with ultra broad-band filter photometry from Gaia EDR3 to derive fu…
rrlfe: Software for Generating and Applying Metallicity Calibrations for RR Lyrae Variable Stars Across a Wide Range of Phases and Temperatures
Eckhart Spalding, Ronald Wilhelm, Nathan De Lee +7
RR Lyrae stars play a central role in tracing phase-space structures within the Milky Way because they are easy to identify, are relatively luminous, and are found in large numbers…
Identification of a Group III CEMP-no Star in the Dwarf Spheroidal Galaxy Canes Venatici I
Jinmi Yoon, Devin D. Whitten, Timothy C. Beers +3
CEMP-no stars, a subclass of carbon-enhanced metal-poor (CEMP) stars, are one of the most significant stellar populations in Galactic Archaeology, because they dominate the low end…
Galactic Archeology with the AEGIS Survey: The Evolution of Carbon and Iron in the Galactic Halo
Jinmi Yoon, Timothy C. Beers, Sarah Dietz +6
Understanding the evolution of carbon and iron in the Milky Way's halo is of importance because these two elements play crucial roles constraining star formation, Galactic assembly…
The R-Process Alliance: 2MASS J09544277+5246414, the Most Actinide-Enhanced R-II Star Known
Erika M. Holmbeck, Timothy C. Beers, Ian U. Roederer +8
We report the discovery of a new actinide-boost star, 2MASS J09544277+5246414, originally identified as a very bright (V = 10.1), extremely metal-poor ([Fe/H] = -2.99) K giant in t…
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…
