Left: 〈e〉 for kinematic thick- versus thin-disk planet hosts with [Fe/H] < 0 and [Fe/H] > 0. [Fe/H] values are taken from T. A. Berger et al. (2020). 〈e〉 is calculated from the underlying eccentricity distribution for each subsample modeled as Rayleigh distributions. The vertical error bars represent the 1σ 〈e〉 uncertainties. Center: same as left panel, but for the single-transit sample. Right: same as left and center panels, but for the multitransit sample.
