We analyze a new kinematic survey that includes accurate proper motions derived from SDSS DR7 positions, combined with multi-epoch measurements from the GSC-II database. By means of the SDSS spectro-photometric data (effective temperature, surface gravity, metallicity, and radial velocities), we estimate photometric parallaxes for a sample of 27 000 FGK (sub)dwarfs with [Fe/H] < -0.5, which we adopted as tracers of the seven-dimensional space distribution (kinematic phase distribution plus… Expand

The thick disk rotation-metallicity correlation as a fossil of an “inverse chemical gradient” in the early Galaxy
Context. The thick disk rotation-metallicity correlation, ∂Vφ/∂[Fe/H] = 40 ÷ 50 km s −1 dex −1 represents an important signature of the formation processes of the galactic disk. Aims. We useExpand

Correlations between age, kinematics, and chemistry as seen by the RAVE survey
We explore the connections between stellar age, chemistry, and kinematics across a Galactocentric distance of 7.5 < R(kpc) < 9.0, using a sample of ∼12 000 intermediate-mass (FGK) turn-off starsExpand
The age structure of stellar populations in the solar vicinity Clues of a two-phase formation history of the Milky Way disk
We analyze a sample of solar neighborhood stars that have high-quality abundance determinations and show that there are two distinct regimes of [α/Fe] versus age, which we identify as the epochs ofExpand
