Logarithm relative abundances [Fe/Mg] as a function of the stellar metallicity [Fe/H] for the 48 rocky exoplanets (triangles for FGK planets and squares for M planets) and for the 1326 planet-hosting stars (orange circles for FGK stars and red circles for M stars). The elemental abundance of planet-hosting stars are taken from the Hypatia Catalog (Hinkel et al. 2014) and the logarithm relative abundances [Fe/Mg] of the 48 rocky exoplanets are calculated from the interior model using the MCMC method.
