A homogeneous analysis of globular clusters from the APOGEE survey with the BACCHUS code. I. The Northern clusters
T. Masseron, D. A. García-Hernández, Sz. Mészáros +12
We analyze a large sample of 885 GCs giants from the APOGEE survey. We used the Cannon results to separate the red giant branch and the asymptotic giant branch stars, not only allo…
The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
Chemical Cartography with APOGEE: Multi-element abundance ratios
David H. Weinberg, Jon A. Holtzman, Sten Hasselquist +25
We map the trends of elemental abundance ratios across the Galactic disk, spanning R = 3-15 kpc and midplane distance |Z|= 0-2 kpc, for 15 elements in a sample of 20,485 stars meas…
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…
The Metal-poor non-Sagittarius (?) Globular Cluster NGC 5053: Orbit and Mg, Al and Si Abundances
Baitian Tang, J. G. Fernandez-Trincado, Doug Geisler +20
Metal-poor globular clusters (GCs) exhibit intriguing Al-Mg anti-correlations and possible Si-Al correlations, which are important clues to decipher the multiple-population phenome…
