Scientific paper

The Radial Velocity Experiment (RAVE) is an ambitious all-sky spectroscopic survey to measure radial velocities and stellar atmosphere parameters (temperature, surface gravity) and abundances of up to one million stars using the 6dF multi-object spectrograph on the 1.2-m UK Schmidt Telescope of the Anglo-Australian Observatory (AAO). RAVE is a multi-national endeavour involving scientists from 10 countries. Since the operation of RAVE started in April 2003, more than 520 000 spectra have been taken in the Ca-triplet region (8410-8790 Å) for southern hemisphere stars in the magnitude range 9 < I < 13 at a resolution of R=7500. The radial velocities measured in this survey are accurate to 2-3 kilometers per second. RAVE has meanwhile published three data releases containing radial velocities, stellar parameters and distance estimates, and a further catalogue containing individual elemantal abundances. Science applications of RAVE include the identification of substructure in the Milky Way and to derive constraints on the gravitational potential of our Galaxy.
