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…

Photo-astrometric distances, extinctions, and astrophysical parameters for Gaia DR2 stars brighter than G = 18

F. Anders, A. Khalatyan, C. Chiappini +19

Combining the precise parallaxes and optical photometry delivered by Gaia's second data release (Gaia DR2) with the photometric catalogues of PanSTARRS-1, 2MASS, and AllWISE, we de…

Kinematics with Gaia DR2: The Force of a Dwarf

I. Carrillo, I. Minchev, M. Steinmetz +10

We use Gaia DR2 astrometric and line-of-sight velocity information combined with two sets of distances obtained with a Bayesian inference method to study the 3D velocity distributi…

The escape speed curve of the Galaxy obtained from Gaia DR2 implies a heavy Milky Way

Giacomo Monari, Benoit Famaey, Ismael Carrillo +6

We measure the escape speed curve of the Milky Way based on the analysis of the velocity distribution of counter-rotating halo stars from the Gaia DR2. The distances we…

Spiral arm crossings inferred from ridges in Gaia stellar velocity distributions

Alice C. Quillen, Ismael Carrillo, Friedrich Anders +7

The solar neighborhood contains disc stars that have recently crossed spiral arms in the Galaxy. We propose that boundaries in local velocity distributions separate stars that have…
