Distributions resulting from the internal structure modeling following Leleu et al. (2021a). The values above the histograms are the median and the 5th and 95th percentiles of the posterior distribution (same as the dashed lines). The plotted internal structure parameters are: the iron core and water mass fractions of the solid planet (without gas); the molar mass fractions of Si and Mg in the mantle and of Fe in the core; and the decimal logarithm of the absolute gas mass expressed in Earth masses.
