Abstract

We present and discuss new determinations of metallicity, rotation, age, kinematics and Galactic orbits for a complete, magnitude-limited, and kinematically unbiased sample of 16682 nearby F and G dwarf stars. Our ~63000 new, accurate radial-velocity observations for nearly 13500 stars allow identification of most of the binary stars in the sample, and together with published uvby-{beta} photometry, Hipparcos parallaxes, Tycho-2 proper motions, and a few earlier radial velocities, complete the kinematic information for 14139 stars. These high-quality velocity data are supplemented by effective temperatures and metallicities newly derived from recent and/or revised calibrations. The remaining stars either lack Hipparcos data or have fast rotation. A major effort has been devoted to the determination of new isochrone ages for all stars for which this is possible. Particular attention has been given to a realistic treatment of statistical biases and error estimates, as standard techniques tend to underestimate these effects and introduce spurious features in the age distributions.
