Comparison between mass–radius relationships computed with the Ma19+ model and those existing in literature. Our mass–radius relationships were computed for WMFs of 20%, 50%, and 100% with no metallic core, and temperatures of 400, 600, 800, and 1000 K. Thin solid lines and thin dashed lines are from Zeng et al. (2016) and Brugger et al. (2017), respectively. Empty triangles, solid circles, and stars correspond to planets subject to no atmospheric escape, to escape of H₂ only, and to escape of both H₂ and H₂O (Jeans or blowoff), respectively. Planetary data are taken from the NASA Exoplanet Archive (https://exoplanetarchive.ipac.caltech.edu) and updated to 2020 July.
