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. GarcÃa-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…
Final Targeting Strategy for the SDSS-IV APOGEE-2N Survey
Rachael L. Beaton, Ryan J. Oelkers, Christian R. Hayes +57
APOGEE-2 is a dual-hemisphere, near-infrared (NIR), spectroscopic survey with the goal of producing a chemo-dynamical mapping of the Milky Way Galaxy. The targeting for APOGEE-2 is…
The Milky Way's bulge star formation history as constrained from its bimodal chemical abundance distribution
Jianhui Lian, Gail Zasowski, Sten Hasselquist +9
We conduct a quantitative analysis of the star formation history (SFH) of the Milky Way's bulge by exploiting the constraining power of its stellar [Fe/H] and [Mg/Fe] distribution…
Orbital Torus Imaging: Using Element Abundances to Map Orbits and Mass in the Milky Way
Adrian M. Price-Whelan, David W. Hogg, Kathryn V. Johnston +9
Many approaches to galaxy dynamics assume that the gravitational potential is simple and the distribution function is time-invariant. Under these assumptions there are traditional…
APOGEE Data Releases 13 and 14: Data and Analysis
Jon A. Holtzman, Sten Hasselquist, Matthew Shetrone +23
Data and analysis methodology used for the SDSS/APOGEE Data Releases 13 and 14 are described, highlighting differences from the DR12 analysis presented in Holtzman (2015). Some imp…
Exploring the Galactic Warp Through Asymmetries in the Kinematics of the Galactic Disk
Xinlun Cheng, Borja Anguiano, Steven R. Majewski +10
Previous analyses of large databases of Milky Way stars have revealed the stellar disk of our Galaxy to be warped and that this imparts a strong signature on the kinematics of star…
