cds-question@unistra.frstellar-agesstellar-massesNew ages are computed for the stars from the Edvardsson et al. (1993, Cat. <J/A+A/275/101>) 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.1998A&A...329..943Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/329/943CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/275/101 : Chemical evolution of the galactic disk I.
