The LSST Data Management System
Mario Jurić, Jeffrey Kantor, K-T Lim +62
The Large Synoptic Survey Telescope (LSST) is a large-aperture, wide-field, ground-based survey system that will image the sky in six optical bands from 320 to 1050 nm, uniformly c…
APOGEE Kinematics I: Overview of the Kinematics of the Galactic Bulge as Mapped by APOGEE
M. Ness, G. Zasowski, J. A. Johnson +12
We present the stellar kinematics across the Galactic bulge and into the disk at positive longitudes from the SDSS-III APOGEE spectroscopic survey of the Milky Way. APOGEE includes…
Magellan/M2FS Spectroscopy of Tucana 2 and Grus 1
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +8
We present results from spectroscopic observations with the Michigan/Magellan Fiber System (M2FS) of stellar targets along the line of sight to the newly-discovered `ultrafai…
IN-SYNC IV - The Young Stellar Population in the Orion A Molecular Cloud
Nicola Da Rio, Jonathan C. Tan, Kevin R. Covey +14
We present the results of the SDSS APOGEE INfrared Spectroscopy of Young Nebulous Clusters program (IN-SYNC) survey of the Orion A molecular cloud. This survey obtained high resolu…
Determining Ages of APOGEE Giants with Known Distances
Diane K Feuillet, Jo Bovy, Jon Holtzman +4
We present a sample of local red giant stars observed using the New Mexico State University 1 m telescope with the APOGEE spectrograph, for which we estimate stellar ages and the a…
Imprints of radial migration on the Milky Way's metallicity distribution functions
Sarah R. Loebman, Victor P. Debattista, David L. Nidever +5
Recent analysis of the SDSS-III/APOGEE Data Release 12 stellar catalogue has revealed that the Milky Way's metallicity distribution function (MDF) changes shape as a function of ra…
ASPCAP: The Apogee Stellar Parameter and Chemical Abundances Pipeline
Ana E. García Pérez, Carlos Allende Prieto, Jon A. Holtzman +27
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) has built the largest moderately high-resolution (R=22, 500) spectroscopic map of the stars across the Milky Way…
Variable stars in the field of the Hydra II ultra-faint dwarf galaxy
A. Katherina Vivas, Knut Olsen, Robert Blum +12
We report the discovery of one RR Lyrae star in the ultra--faint satellite galaxy Hydra II based on time series photometry in the g, r and i bands obtained with the Dark Energy Cam…
The Apache Point Observatory Galactic Evolution Experiment (APOGEE)
Steven R. Majewski, Ricardo P. Schiavon, Peter M. Frinchaboy +75
The Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of the programs in the Sloan Digital Sky Survey III (SDSS-III), has now completed its systematic, homogeneo…
The stellar population structure of the Galactic disk
Jo Bovy, Hans-Walter Rix, Edward F. Schlafly +4
The spatial structure of stellar populations with different chemical abundances in the Milky Way contains a wealth of information on Galactic evolution over cosmic time. We use dat…
IN-SYNC III: The dynamical state of IC 348 - A super-virial velocity dispersion and a puzzling sign of convergence
Michiel Cottaar, Kevin R. Covey, Jonathan B. Foster +11
Most field stars will have encountered the highest stellar density and hence the largest number of interactions in their birth environment. Yet the stellar dynamics during this cru…
Rapid Rotation of Low-Mass Red Giants Using APOKASC: A Measure of Interaction Rates on the Post-main-sequence
Jamie Tayar, Tugdual Ceillier, D. A. García-Hernández +16
We investigate the occurrence rate of rapidly rotating (10 km s), low-mass giant stars in the APOGEE-Kepler (APOKASC) fields with asteroseismic mass and surface…
Hydra II: a faint and compact Milky Way dwarf galaxy found in the Survey of the Magellanic Stellar History
Nicolas F. Martin, David L. Nidever, Gurtina Besla +26
We present the discovery of a new dwarf galaxy, Hydra II, found serendipitously within the data from the ongoing Survey of the MAgellanic Stellar History (SMASH) conducted with the…
Young [/Fe]-enhanced stars discovered by CoRoT and APOGEE: What is their origin?
C. Chiappini, F. Anders, T. S. Rodrigues +34
We report the discovery of a group of apparently young CoRoT red-giant stars exhibiting enhanced [alpha/Fe] abundance ratios (as determined from APOGEE spectra) with respect to Sol…
Chemical Cartography with APOGEE: Metallicity Distribution Functions and the Chemical Structure of the Milky Way Disk
Michael R. Hayden, Jo Bovy, Jon A. Holtzman +32
Using a sample of 69,919 red giants from the SDSS-III/APOGEE Data Release 12, we measure the distribution of stars in the [/Fe] vs. [Fe/H] plane and the metallicity distribution…
The APOGEE Spectroscopic Survey of Kepler Planet Hosts: Feasibility, Efficiency, and First Results
Scott W. Fleming, Suvrath Mahadevan, Rohit Deshpande +33
The Kepler mission has yielded a large number of planet candidates from among the Kepler Objects of Interest (KOIs), but spectroscopic follow-up of these relatively faint stars is…
The Puzzling Li-rich Red Giant Associated with NGC 6819
