Analysis of Previously Classified White Dwarf-Main Sequence Binaries Using Data from the APOGEE Survey
Kyle A. Corcoran, Hannah M. Lewis, Borja Anguiano +12
We present analyses of near-infrared, spectroscopic data from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey for 45 previously confirmed or candidate wh…
Exploring the Galactic Warp Through Asymmetries in the Kinematics of the Galactic Disk
Xinlun Cheng, Borja Anguiano, Steven R. Majewski +10
Previous analyses of large databases of Milky Way stars have revealed the stellar disk of our Galaxy to be warped and that this imparts a strong signature on the kinematics of star…
Geometry of the Draco C1 Symbiotic Binary
Hannah M. Lewis, Borja Anguiano, Keivan G. Stassun +14
Draco C1 is a known symbiotic binary star system composed of a carbon red giant and a hot, compact companion -- likely a white dwarf -- belonging to the Draco dwarf spheroidal gala…
Exploring the stellar age distribution of the Milky Way Bulge using APOGEE
Sten Hasselquist, Gail Zasowski, Diane K. Feuillet +20
We present stellar age distributions of the Milky Way (MW) bulge region using ages for 6,000 high-luminosity (), metal-rich () bulge stars…
The Close Binary Fraction as a Function of Stellar Parameters in APOGEE: A Strong Anti-Correlation With Abundances
Christine N. Mazzola, Carles Badenes, Maxwell Moe +20
We use observations from the APOGEE survey to explore the relationship between stellar parameters and multiplicity. We combine high-resolution repeat spectroscopy for 41,363 dwarf…
The stellar velocity distribution function in the Milky Way galaxy
Borja Anguiano, Steven R. Majewski, Chris R. Hayes +6
The stellar velocity distribution function (DF) in the solar vicinity is re-examined using data from the SDSS APOGEE survey's DR16 and \emph{Gaia} DR2. By exploiting APOGEE's abili…
The Sixth Data Release of the Radial Velocity Experiment (RAVE) -- II: Stellar Atmospheric Parameters, Chemical Abundances and Distances
Matthias Steinmetz, Guillaume Guiglion, Paul J. McMillan +58
We present part 2 of the 6th and final Data Release (DR6 or FDR) of the Radial Velocity Experiment (RAVE), a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars rando…
The Sixth Data Release of the Radial Velocity Experiment (RAVE) -- I: Survey Description, Spectra and Radial Velocities
Matthias Steinmetz, Gal Matijevic, Harry Enke +59
The Radial Velocity Experiment (RAVE) is a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars randomly selected in the southern hemisphere. The RAVE medium-resolutio…
