Mass–radius relationships for planets with Earthlike properties regarding their rocky part (see Table 1), and computed with ﹩{\gamma }_{+}﹩, for multiple temperatures and water contents. Colors correspond to the three used EOSs: DZ06 (red), WP02 (blue), and Ma19 (green). Dashed lines correspond to regions where the atmospheric model is extrapolated beyond the available grid (see Appendix B). Filled circles correspond to cases where both P and γ remain in the range of validity of the used EOSs. Open circles correspond to cases where P or γ are computed in the extended range. Crosses correspond to cases where P or γ are in the extrapolated range. Shaded areas correspond to H₂ (gray), H₂O (pink), and hydrodynamic escape (shaded) (see Section 4).
