| Description | Using RAVE data release 5 (DR5), we explore the age and chemistry of a sample of ~25,000 FGK turnoff stars in the extended solar neighbourhood (7 < R < 9 kpc), by separating our sample into two chemical disc components, and investigating the nature of the age-metallicity relation for both. Overall, we find a flat trend in [Fe/H] as a function of age for our α-low disc, and a correlation between age and metallicity for the oldest α-high stars, confirming age-metallicity trends found in more local, high-resolution studies now for a larger volume. We also find a positive gradient in [Mg/Fe] as a function of age for our oldest stars. These results have implications for models which include dynamical evolutionary processes such as radial migration. |
