New ages are computed for stars in the Solar Neighbourhood from the
Edvardsson et al. (1993) data set. Distances derived from the Hipparcos
parallaxes were adopted to obtain reliable ages (uncertainty less than 12%) for
a subset of stars. There is no apparent age-metallicity relation for stars with
an age less than 10 Gyr. Only if we consider older stars a slope of ~0.07
dex/Gyr appears. This relation is compared with those obtained from other
methods, i.e. galactic open clusters, stellar population synthesis (star
counts), and chemical evolution models.Comment: 4 pages LaTeX, 3 postscript figures, to appear in proceedings ``1997
