Revised ages for stars in the solar neighbourhood.
NG Y.K. and BERTELLI G.
Abstract (from CDS):
New ages are computed for the stars from the Edvardsson et al. (1993A&A...275..101E) data set. The revised values are systematically larger toward older ages (t>4Gyr), while they are slightly lower for t<4Gyr. A similar, but considerably smaller trend is present when the ages are computed with the distances based on Hipparcos parallaxes. The resulting age-metallicity relation has a small, but distinct slope of ∼0.07dex/Gyr.
