Abstract:
We investigate radial and vertical metallicity gradients for a sample
of red clump stars from the RAdial Velocity Experiment (RAVE) Data
Release 3. We select a total of 6781 stars, using a selection of
colour, surface gravity and uncertainty in the derived space motion,
and calculate for each star a probabilistic (kinematic) population
assignment to a thin or thick disc using space motion and additionally
another (dynamical) assignment using stellar vertical orbital
eccentricity.
