Fig. 1

Compositional diversity of stars in the Solar neighborhood in the molar Mg–Fe–Si system, as recorded in the Hypatia Catalog (Hinkel et al. 2014). Each red dot represents a star, while the yellow triangle represents the Solar composition from Asplund et al. (2005), which was also used for converting abundances from the Hypatia catalog. The yellow dot shows Earth’s composition (McDonough 2003).
