Mean [C/Fe] abundance ratios as a function of the stellar metallicity. Same as in Fig. 4 but showing our stars colour-coded according to their effective temperature (top panel), peculiar space velocity (middle panel), and orbital eccentricity (bottom panel) from Magrini et al. (2022). In the bottom panel, the symbol sizes are proportional to the difference between the mean distance of the stars in their Galactic orbit (R_mean) and their current galactocentric distance (R_GC).
