Compilation of [El/Fe I] trends as a function of age for the thin-disc stars. The continuous purple lines represent the r-process dominated elements Eu, Sm, and Pr. The thick dash-dotted line is an averaged trend of these element-to-iron abundance ratios. The continuous blue lines represent the s-process dominated elements Y, Sr, and Ba. The thick dash-dotted line is an averaged trend of these element-to-iron abundance ratios. The grey continuous lines are for elements with negligible [El/Fe I] age trends (Nd, Ce, La, and Zr). The continuous magenta line represents the [Mg/Fe I] age correlation. The shadowed areas show the 95% confidence interval for the regressions. The vertical dashed line marks the solar age.
