Conclusions<br />
• We have detected a <strong>rotation</strong>/<strong>metallicity</strong> <strong>correlation</strong> in <strong>the</strong><br />
<strong>thick</strong> <strong>disk</strong> population that represents an important<br />
signature of <strong>the</strong> formation processes of <strong>the</strong> galactic <strong>disk</strong>s<br />
• For <strong>the</strong> first time, high resolution N-Body models can<br />
account for a similar <strong>correlation</strong>, Vphi-[Fe/H], produced by<br />
<strong>the</strong> stellar radial migration, if we assume an initial<br />
«inverse» chemical gradient in <strong>the</strong> inner <strong>disk</strong><br />
• This scenario, based on local observations, appears<br />
consistent with <strong>the</strong> properties of isolated <strong>disk</strong> galaxies at<br />
high redshift
