Left panels: variation of abundance indicators, as a function of seismic age. The data are colour-coded as a function of T_eff. The thin- and thick-disc stars are shown as circles and squares, respectively. The solar age is shown as a vertical dotted line. Middle and right panels: same as left panels, but colour-coded as a function of [Fe/H] and M, respectively. Linear 1D relations in the literature linking abundance ratios and ages are overplotted as dashed lines: Bedell et al. (2018, red), DM19 (blue), Nissen (2016) and Nissen et al. (2020, cyan), Spina et al. (2018, magenta), Titarenko et al. (2019, yellow), and Tucci Maia et al. (2016, green).
