Two Groups of Red Giants with Distinct Chemical Abundances in the Bulge Globular Cluster NGC 6553 Through the Eyes of APOGEE
Baitian Tang, Roger E. Cohen, Doug Geisler +18
Multiple populations revealed in globular clusters (GCs) are important windows to the formation and evolution of these stellar systems. The metal-rich GCs in the Galactic bulge are…
Red giants observed by CoRoT and APOGEE: The evolution of the Milky Way's radial metallicity gradient
F. Anders, C. Chiappini, I. Minchev +21
Using combined asteroseismic and spectroscopic observations of 418 red-giant stars close to the Galactic disc plane (6 kpc kpc, kpc), w…
Studying the evolution of AGB stars in the Gaia epoch
M. Di Criscienzo, P. Ventura, D. A. Garcia-Hernandez +6
We present asymptotic giant branch (AGB) models of solar metallicity, to allow the interpretation of observations of Galactic AGB stars, whose distances should be soon available af…
Discovery of a Metal-Poor Field Giant with a Globular Cluster Second-Generation Abundance Pattern
J. G. Fernández-Trincado, A. C. Robin, E. Moreno +31
We report on detection, from observations obtained with the APOGEE spectroscopic survey, of a metal-poor ([Fe/H] dex) field giant star with an extreme Mg-Al abundance rati…
Chemical abundance gradients from open clusters in the Milky Way disk: results from the APOGEE survey
Katia Cunha, Peter M. Frinchaboy, Diogo Souto +23
Metallicity gradients provide strong constraints for understanding the chemical evolution of the Galaxy. We report on radial abundance gradients of Fe, Ni, Ca, Si, and Mg obtained…
