Abstract

We performed N-body simulations to study the dynamical evolution of a stellar disk inside a Dark Matter (DM) halo. Our results evidence how a standard -radially decreasing- metallicity gradient produces a negative v_ϕ vs. [Fe/H] correlation, similar to that shown by the thin disk stars, while an inverse radial gradient generates a positive rotation-metallicity correlation, as that observed in the old thick population.
