This is the second public data release of the RAVE project. At the time of its publication it has been the largest database of stellar radial velocities and of spectroscopically determined values of stellar parameters (temperature, gravity, metallicity). The article has 44 clean citations (up to april 2011).

The paper studies the properties of the diffuse interstellar band at 862 nm. It shows that its equivalent width is strictly proportional to the reddening or to the value of the color excess. This may be important in the attempts to pinpoint the physical origins of this diffuse interstellar band.

We find that the local volumes of the solar neighbourhood sampled by the CORAVEL and RAVE are devoid of any vertically coherent streams containing hundreds of stars. This is sufficiently sensitive to allow our RAVE sample to rule out the passing of the tidal stream of the disrupting Sagittarius (Sgr) dwarf galaxy through the solar neighbourhood. This argues against the Virgo over-density crossing the disc near the Sun.

Our analysis is based on a sample of high-velocity stars from the RAVE survey and two previously published data sets. We find that the local escape velocity from our Galaxy lies within the range 498 .. 608km/s (90 per cent confidence), with a median likelihood of 544 km/s. The fact that escape velocity is significantly greater than 1.41 times the local circular velocity implies that there must be a significant amount of mass exterior to the solar circle, that is, this convincingly demonstrates the presence of a dark halo in the Galaxy. We estimate its mass at ~ 1.41E12 Solar masses.

Very metal-poor stars are of obvious importance for many problems in chemical evolution, star formation, and galaxy evolution. We demonstrate here that stars with iron abundances [Fe/H] <-2 dex, and down to below -4 dex, can be efficiently identified within the Radial Velocity Experiment (RAVE) survey of bright stars, without requiring additional confirmatory observations. We identify 631 stars with [Fe/H] <=-2, three with extremely low metallicities. Relatively large numbers of metal poor stars allow their population analysis.
