Fig. 1

Distribution of eccentricities as a function of orbital period. Only eccentricities measured with uncertainties smaller than 0.1 are shown. Planets are arbitrarily separated in three categories by radius: Jupiter-size (red, top panel), Neptune-size (green, middle panel), and Earth-size (blue, bottom panel). In the middle panel, black squares highlight three iconic planets representative of the warm Neptunes population.
