RAVE (RAdial Velocity Experiment) is a multi-fiber spectroscopic astronomical survey of stars in the Milky Way using the 1.2-m UK Schmidt Telescope of the Australian Astronomical Observatory (AAO). The RAVE collaboration consists of researchers from over 20 institutions around the world and is coordinated by the Leibniz-Institut für Astrophysik Potsdam.
As a southern hemisphere survey covering 20,000 square degrees of the sky, RAVE’s primary aim is to derive the radial velocity of stars from the observed spectra. Additional information is also derived such as effective temperature, surface gravity, metallicity, photometric parallax and elemental abundance data for the stars. The survey represents a giant leap forward in our understanding of our own Milky Way galaxy; with RAVE’s vast stellar kinematic database the structure, formation and evolution of our Galaxy can be studied.
From 2003 to 2013 (end of observation campaign), RAVE has obtained 574,630 spectra of 483,330 unique stars in the magnitude range 8 < I < 12 mag. This represents stellar distances up to ∼ 3 kpc from the Sun. The covered spectral region (8410–8794 Å) contains the infrared Calcium triplet and is similar to the wavelength range chosen for Gaia’s Radial Velocity Spectrometer. The effective resolution of R = λ/∆λ ∼ 7, 000 enables us to measure line-of-sight velocities with a median precision better than 1.5 km/s, as well as good precision atmospheric parameters and chemical abundances for the surveyed stars.
