“Modified” tidal diagram for 232 giant planets with uniformly derived eccentricities (Bonomo et al. 2017b). Black empty circles show the position of giant planets with well-determined circular orbits, i.e. with eccentricities consistent with zero and 1σ uncertainty σ_e < 0.05; grey crosses indicate planets with undetermined eccentricities which are usually consistent with zero but have large uncertainties σ_e > 0.05; orange triangles show small but significant eccentricities, i.e. e < 0.1; and blue squares e ≥ 0.1. The position of KOI-3680b is indicated in the upper-right corner. The dotted, dash-dotted, and dash-three-dotted lines display the 1, 7, and 14 Gyr circularization timescales for a planetary modified tidal quality factor and e = 0, respectively.
