Chemical Cartography with APOGEE: Large-scale Mean Metallicity Maps of the Milky Way
Michael R. Hayden, Jon A. Holtzman, Jo Bovy +27
We present Galactic mean metallicity maps derived from the first year of the SDSS-III APOGEE experiment. Mean abundances in different zones of Galactocentric radius (0 < R < 15 kpc…
Discovery of a Dynamical Cold Point in the Heart of the Sagittarius dSph Galaxy with Observations from the APOGEE Project
Steven R. Majewski, Sten Hasselquist, Ewa L. Łokas +30
The dynamics of the core of the Sagittarius (Sgr) dwarf spheroidal (dSph) galaxy are explored using high-resolution (R~22,500), H-band, near-infrared spectra of over 1,000 giant st…
The Open Cluster Chemical Analysis and Mapping Survey: Local Galactic Metallicity Gradient with APOGEE using SDSS DR10
Peter M. Frinchaboy, Benjamin Thompson, Kelly M. Jackson +31
The Open Cluster Chemical Analysis and Mapping (OCCAM) Survey aims to produce a comprehensive, uniform, infrared-based dataset for hundreds of open clusters, and constrain key Gala…
The Tenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-III Apache Point Observatory Galactic Evolution Experiment
Christopher P. Ahn, Rachael Alexandroff, Carlos Allende Prieto +232
The Sloan Digital Sky Survey (SDSS) has been in operation since 2000 April. This paper presents the tenth public data release (DR10) from its current incarnation, SDSS-III. This da…
MARVELS-1: A face-on double-lined binary star masquerading as a resonant planetary system; and consideration of rare false positives in radial velocity planet searches
Jason T. Wright, Arpita Roy, Suvrath Mahadevan +24
We have analyzed new and previously published radial velocity observations of MARVELS-1, known to have an ostensibly substellar companion in a ~6- day orbit. We find significant (~…
Very Metal-poor Stars in the Outer Galactic Bulge Found by the Apogee Survey
Ana E. García Pérez, Katia Cunha, Matthew Shetrone +27
Despite its importance for understanding the nature of early stellar generations and for constraining Galactic bulge formation models, at present little is known about the metal-po…
