The Age-Metallicity Relation for the Field Disk Stars in the Solar Neighborhood
The ages of field stars given in the catalogue of Cayrel de Strobel et al.(1985) are derived by the five different methods with combination of theoretical isochrones. By using these ages and metal abundances homogenized by Lee and Choe(1988), the age-metallicity relations are obtained. For disk stars of [Fe/H] > -0.9, the present age-metallicity relations are nearly consistent with those given by Twarog(1980) and Carlberg et al.(1985).
