Journal ArticleDOI
Open Cluster Chemical Homogeneity throughout the Milky Way
Vijith Jacob Poovelil,Gail Zasowski,Sten Hasselquist,Anil C. Seth,John Donor,Rachael L. Beaton,Katia Cunha,Peter M. Frinchaboy,D. A. García-Hernández,Keith Hawkins,Kaitlin M. Kratter,Richard R. Lane,Christian Nitschelm +12 more
TL;DR: The chemical homogeneity of surviving stellar clusters contains important clues about interstellar medium (ISM) mixing efficiency, star formation, and the enrichment history of the Galaxy as discussed by the authors, which would have implications for Galactic chemical evolution models and the feasibility of chemical tagging.
Journal ArticleDOI
Lithium Inventory of 2 $M_\odot$ Red Clump Stars in Open Clusters: A Test of the Helium Flash Mechanism
TL;DR: In this paper, the authors measured abundances in 38 Li-rich red clump stars and 6 red giant branch (RGB) stars in four open clusters selected to have RC masses near 2 $M_\odot$.
Journal ArticleDOI
CARBON ABUNDANCES OF THREE CARBON-ENHANCED METAL-POOR STARS FROM HIGH-RESOLUTION GEMINI-S/bHROS SPECTRA OF THE λ8727 [C I] LINE
Simon C. Schuler,S. J. Margheim,Thirupathi Sivarani,Thirupathi Sivarani,Martin Asplund,Verne V. Smith,Katia Cunha,Timothy C. Beers +7 more
TL;DR: In this article, the results from an analysis of the λ8727 forbidden [C I] line in high-resolution Gemini-S/bHROS spectra of three Carbon-Enhanced Metal-poor (CEMP) stars are presented.
Journal ArticleDOI
CAPOS: The bulge Cluster APOgee Survey I. Overview and initial ASPCAP results

TL;DR: CAPOS as discussed by the authors uses the APOGEE-2S spectrograph observing in the H band to penetrate obscuring dust toward the bulge and obtain accurate mean values for these parameters, as well as abundances for a number of other elements.
Journal ArticleDOI

TL;DR: In this paper, an analysis of the 8727ang forbidden [C I] line in high-resolution Gemini-S/bHROS spectra of three CEMP stars is presented.
