Solid (left) and elemental mass fractions (right) of solid material formed completely interior to the water ice line (T > 150 K) around a star with [Fe/H] = −0.2 (top) and [Fe/H] = −0.4 (bottom). As for [Fe/H] = 0 (Fig. 2), the solid composition is dominated by Mg₂SiO₄ and MgSiO₃, while the elemental composition is dominated by oxygen and iron, making up around 60% of the total mass of the planet.
