Solar Neighbourhood Age–Metallicity Relation

What is it about?

We investigated the age–metallicity relation using a sample of 5691 F- and G-type dwarfs in terms of their effective temperatures and population types. The largest age–metallicity slope was found for early F-type dwarfs. We noticed a substantial scatter in metallicity distribution at all ages. The metal-rich old dwarfs turned out to be G-type stars which can be interpreted as they migrated from the inner disc or bulge.
