The vertical metallicity gradients of mono-age stellar populations in the Milky Way with the RAVE and Gaia data

Ciuca, Ioana; Kawata, D.; Lin, Jinying (Jane); Casagrande, Luca; Seabroke, G. M; Cropper, Mark


We investigate the vertical metallicity gradients of five mono-age stellar populations between 0 and 11 Gyr for a sample of 18 435 dwarf stars selected from the cross-matched Tycho-Gaia Astrometric Solution and Radial Velocity Experiment (RAVE) Data Release 5. We find a correlation between the vertical metallicity gradients and age, with no vertical metallicity gradient in the youngest population and an increasingly steeper negative vertical metallicity gradient for the older stellar...[Show more]
