  • The age-metallicity relation for F and G dwarf stars in the solar neighborhood, based on the stellar metallicity data of Edvardsson et al., shows an apparent scatter that is larger than expected considering the uncertainties in metallicities and ages. A number of theoretical models have been put forward to explain the large scatter. However, we present evidence, based on the Edvardsson et al. data, along with Hipparcos parallaxes and new age estimates, that the scatter in the age-metallicity… CONTINUE READING
