Left: CDFs of the stellar metallicity distributions [Fe/H] for the thick- and thin-disk stellar samples. [Fe/H] values for individual stars are those published by T. A. Berger et al. (2020). The sample of thick-disk planet hosts is shown in red, and thin-disk planet hosts are shown in teal. Right: CDFs of stellar age (Gyr) for thin- and thick-disk planet hosts with T_eff > 4700 K. Age estimates are those published by T. A. Berger et al. (2020).
