Revised ages for the stars in the solar neighbourhood | Y.K. Ng
; G. Bertelli
; | Date: |
3 Jul 1997 | Subject: | astro-ph | Abstract: | New ages are computed for the stars from the Edvardsson et al. (1993) data set. The revised values are systematically larger toward older ages (t>4 Gyr), while they are slightly lower for t<4 Gyr. 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 about 0.07 dex/Gyr | Source: | arXiv, astro-ph/9707043 | Services: | Forum | Review | PDF | Favorites |
