SPLUSJ210428.01-004934.2: An Ultra Metal-Poor Star Identified from Narrowband Photometry
Vinicius M. Placco, Ian U. Roederer, Young Sun Lee +6
We report on the discovery of SPLUS J210428.01-004934.2, an ultra metal-poor (UMP) star first identified from the narrow-band photometry of the Southern Photometric Local Universe…
Evidence For Multiple Accretion Events in the -Sausage/Enceladus Structures
Young Kwang Kim, Young Sun Lee, Timothy C. Beers +1
We present evidence that multiple accretion events are required to explain the origin of the -Sausage and Enceladus (GSE) structures, based on an analysis of dynamical proper…
Origin and Status of Low-Mass Candidate Hypervelocity Stars
Bum-Suk Yeom, Young Sun Lee, Jae-Rim Koo +2
We present an analysis of the chemical abundances and kinematics of six low-mass dwarf stars, previously claimed to be candidate hypervelocity stars (HVSs). We obtained moderate-re…
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…
Carbon in Red Giants in Globular Clusters and Dwarf Spheroidal Galaxies
Evan N. Kirby, Michelle Guo, Andrew J. Zhang +6
We present carbon abundances of red giants in Milky Way globular clusters and dwarf spheroidal galaxies (dSphs). Our sample includes measurements of carbon abundances for 154 giant…
