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…
APOGEE Data Releases 13 and 14: Stellar Parameter and Abundance Comparisons With Independent Analyses
Henrik Jönsson, Carlos Allende Prieto, Jon A. Holtzman +18
Data from the SDSS-IV / Apache Point Observatory Galactic Evolution Experiment (APOGEE-2) have been released as part of SDSS Data Releases 13 (DR13) and 14 (DR14). These include hi…
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…
A comprehensive comparison between APOGEE and LAMOST: Radial Velocities and Atmospheric Stellar Parameters
B. Anguiano, S. R. Majewski, C. Allende-Prieto +7
We undertake a critical and comprehensive comparison of the radial velocities and the main stellar atmospheric parameters for stars in common between the latest data releases from…
A chemical and kinematical analysis of the intermediate-age open cluster IC 166 from APOGEE and Gaia DR2
J. Schiappacasse-Ulloa, B. Tang, J. G. Fernández-Trincado +26
IC 166 is an intermediate-age open cluster ( Gyr) which lies in the transition zone of the metallicity gradient in the outer disc. Its location, combined with our very limi…
Stellar and Planetary Characterization of the Ross 128 Exoplanetary System from APOGEE Spectra
Diogo Souto, Cayman T. Unterborn, Verne V. Smith +14
The first detailed chemical abundance analysis of the M dwarf (M4.0) exoplanet-hosting star Ross 128 is presented here, based upon near-infrared (1.5--1.7 \micron) high-resolution…
Chemical abundances of hydrostatic and explosive alpha-elements in Sagittarius stream stars
Jeffrey L. Carlin, Allyson A. Sheffield, Katia Cunha +1
We analyze chemical abundances of stars in the Sagittarius (Sgr) tidal stream using high-resolution Gemini+GRACES spectra of 42 members of the highest surface brightness portions o…
Disk-Like Chemistry of the Triangulum-Andromeda Overdensity as Seen by APOGEE
Christian R. Hayes, Steven R. Majewski, Sten Hasselquist +15
The nature of the Triangulum-Andromeda (TriAnd) system has been debated since the discovery of this distant, low-latitude Milky Way (MW) overdensity more than a decade ago. Explana…
The Second APOKASC Catalog: The Empirical Approach
Marc H. Pinsonneault, Yvonne P. Elsworth, Jamie Tayar +33
We present a catalog of stellar properties for a large sample of 6676 evolved stars with APOGEE spectroscopic parameters and \textit{Kepler} asteroseismic data analyzed using five…
Chemical Abundances of Main-Sequence, Turn-off, Subgiant and red giant Stars from APOGEE spectra I: Signatures of Diffusion in the Open Cluster M67
Diogo Souto, Katia Cunha, Verne V. Smith +21
Detailed chemical abundance distributions for fourteen elements are derived for eight high-probability stellar members of the solar metallicity old open cluster M67 with an age of…
