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 DR14/DR15 Abundances in the Inner Milky Way
G. Zasowski, M. Schultheis, S. Hasselquist +14
We present an overview of the distributions of 11 elemental abundances in the Milky Way's inner regions, as traced by APOGEE stars released as part of SDSS Data Release 14/15 (DR14…
Discovery of a disrupting open cluster far into the Milky Way halo: a recent star formation event in the leading arm of the Magellanic stream?
Adrian M. Price-Whelan, David L. Nidever, Yumi Choi +4
We report the discovery of a young (), low-mass (), metal-poor () stellar association at a he…
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…
A Lonely Giant: The Sparse Satellite Population of M94 Challenges Galaxy Formation
Adam Smercina, Eric F. Bell, Paul A. Price +5
The dwarf satellites of `giant' Milky Way (MW)-mass galaxies are our primary probes of low-mass dark matter halos. The number and velocities of the satellite galaxies of the MW and…
44 New & Known M Dwarf Multiples In The SDSS-III/APOGEE M Dwarf Ancillary Science Sample
Jacob Skinner, Kevin R. Covey, Chad F. Bender +28
Binary stars make up a significant portion of all stellar systems. Consequently, an understanding of the bulk properties of binary stars is necessary for a full picture of star for…
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…
Exploring the Very Extended Low Surface Brightness Stellar Populations of the Large Magellanic Cloud with SMASH
David L. Nidever, Knut Olsen, Yumi Choi +23
We present the detection of very extended stellar populations around the Large Magellanic Cloud (LMC) out to R~21 degrees, or ~18.5 kpc at the LMC distance of 50 kpc, as detected i…
SMASHing THE LMC: Mapping a Ring-like Stellar Overdensity in the LMC Disk
Yumi Choi, David L. Nidever, Knut Olsen +18
We explore the stellar structure of the Large Magellanic Cloud (LMC) disk using data from the Survey of the MAgellanic Stellar History (SMASH) and the Dark Energy Survey. We detect…
The APOGEE-2 Survey of the Orion Star Forming Complex: I. Target Selection and Validation with early observations
J'Neil Cottle, Kevin R. Covey, Genaro Suárez +26
The Orion Star Forming Complex (OSFC) is a central target for the APOGEE-2 Young Cluster Survey. Existing membership catalogs span limited portions of the OSFC, reflecting the diff…
Binary companions of evolved stars in APOGEE DR14: Search method and catalog of ~5,000 companions
Adrian M. Price-Whelan, David W. Hogg, Hans-Walter Rix +10
Multi-epoch radial velocity measurements of stars can be used to identify stellar, sub-stellar, and planetary-mass companions. Even a small number of observation epochs can be info…
SMASHing the LMC: A Tidally-induced Warp in the Outer LMC and a Large-scale Reddening Map
Yumi Choi, David L. Nidever, Knut Olsen +18
We present a study of the three-dimensional (3D) structure of the Large Magellanic Cloud (LMC) using ~2.2 million red clump (RC) stars selected from the Survey of the MAgellanic St…
Ships Passing in the Night: Spectroscopic Analysis of Two Ultra-Faint Satellites in the Constellation Carina
T. S. Li, J. D. Simon, A. B. Pace +21
We present Magellan/IMACS, Anglo-Australian Telescope/AAOmega+2dF, and Very Large Telescope/GIRAFFE+FLAMES spectroscopy of the CarinaII (Car II) & Carina III (Car III) dwarf galaxy…
First Data Release of the All-sky NOAO Source Catalog
David L. Nidever, Arjun Dey, Knut Olsen +6
Most of the sky has been imaged with NOAO's telescopes from both hemispheres. While the large majority of these data were obtained for PI-led projects and almost all of the images…
