A simple model for the evolution of an isothermal disk has been developed. It combines both the chemical evolution (through the Age-Metallicity Relation) and dynamical evolution (through the age-dispersion relation). Applying this model to a sample of Red Clump Stars from the Tycho-2 catalog, observed with the high resolution echelle spectrograph Elodie at the Observatoire de Haute Provence, we derive the underlying Star Formation History and compare it with local determinations using chromospheric activity survey by Rocha-Pinto et al. (2000b).
