Solid (left) and elemental mass fractions (right) of solid planetary building blocks formed completely exterior to the water ice line (T < 150 K) around a star with [Fe/H] = +0.2 (top) and [Fe/H] = +0.4 (bottom). In contrast to the mass fractions of solids formed around lower metallicity stars exterior to the water ice line, the dominant solids mass is not water ice, but Mg2SiO4. In fact, the water ice content is reduced to just a few percent for solids formed around stars with [Fe/H] = 0.4. The dominant elemental mass fraction is oxygen and iron, however the oxygen fraction is not as elevated as for planets formed around stars with low [Fe/H], see Fig. 5.
