Galactic Archeology with RAVE and TGAS

Abstract

The 5th RAVE data release is based on 520,781 spectra (R ≈ 7500 in the CaT region at 8410 -8795Å) of 457,588 unique stars. RAVE DR5 provides radial velocities, stellar parameters and individual abundances for up to seven elements and distances found using isochrones for a considerable subset of these objects. In particular, RAVE DR5 has 255,922 stellar observations that also have parallaxes and proper motions from the Tycho-Gaia astrometric solution (TGAS) in Gaia DR1. The combination of RAVE and TGAS thus pr…
