Comparison of the CMF of the rocky exoplanets with the equivalent stellar CMF_star. The CMF_star values were calculated from the Fe/Mg ratio of the host stars using Eq. (7) with the Earth-like mantle composition [Si/Mg = 0.96, Al/Mg = 0.09, Ca/Mg = 0.07, and assuming no iron in the mantle, f_Feo = 0 (Adibekyan et al. 2021; Brinkman et al. 2024)]. The rocky planets depicted by thin rhombuses are classified as super-Mercuries, while those illustrated with circles are identified as super-Earths. Solid and dashed black lines denote the ODR and OLS fits to the sample of the super-Earths, respectively.
