Caption: Figure 8.
All transiting exoplanets in the range of 6–20 Earth radii. Planets with periods less than 100 days are plotted in light gray, and the 16 planets with periods longer than 100 days are plotted in black. TOI-6692 b is plotted as a blue filled star. The gray region illustrates planets that are likely undergoing high-eccentricity tidal migration. The upper and lower limits of the track are set by the Roche limit and the tidal circularization timescale (J. Dong et al. 2021). The dotted–dashed line presents the theoretical upper limit of eccentricities as a result of planet–planet scattering, assuming a planet with a mass of 0.5 MJup and a radius of 2 RJup, for illustrative purposes (C. Petrovich et al. 2014). Data were obtained on 2025 August 4 from the NASA Exoplanet Archive.
