Corner plot depicting the interior structure model of TOI-4552b using exopie (Plotnykov & Valencia 2024) with the planetary mass and radius as priors. The abundance of iron in the mantle and silicon in the core is left to vary freely between 0 and 20%. The resulting CMF of 0.54 is partway between that of Mercury (= 0.7; Szurgot 2015) and Earth (= 0.33), suggesting a marginal over-abundance of iron (also evident from the high iron mass fraction, Fe-MF).
