Metallicity and -element Abundance Gradients along the Sagittarius Stream as Seen by APOGEE
Christian R. Hayes, Steven R. Majewski, Sten Hasselquist +27
Using 3D positions and kinematics of stars relative to the Sagittarius (Sgr) orbital plane and angular momentum, we identify 166 Sgr stream members observed by the Apache Point Obs…
Homogeneous Analysis of Globular Clusters from the APOGEE Survey with the BACCHUS Code. II. The Southern Clusters and Overview
Szabolcs Mészáros, Thomas Masseron, D. A. García-Hernández +33
We investigate the Fe, C, N, O, Mg, Al, Si, K, Ca, Ce and Nd abundances of 2283 red giant stars in 31 globular clusters from high-resolution spectra observed in both the northern a…
Reduction of the maximum mass-loss rate of OH/IR stars due to unnoticed binary interaction
L. Decin, W. Homan, T. Danilovich +12
In 1981, the idea of a superwind that ends the life of cool giant stars was proposed. Extreme OH/IR-stars develop superwinds with the highest mass-loss rates known so far, up to a…
Constraining Metallicity-dependent Mixing and Extra Mixing using [C/N] in Alpha-Rich Field Giants
Matthew Shetrone, Jamie Tayar, Jennifer A. Johnson +11
Internal mixing on the giant branch is an important process which affects the evolution of stars and the chemical evolution of the galaxy. While several mechanisms have been propos…
The Lazy Giants: APOGEE Abundances Reveal Low Star Formation Efficiencies in the Magellanic Clouds
David L. Nidever, Sten Hasselquist, Christian R. Hayes +28
We report the first APOGEE metallicities and alpha-element abundances measured for 3600 red giant stars spanning a large radial range of both the Large (LMC) and Small Magellanic C…
