Mg/Si versus Al/Si weight ratios for the sample of the simulated planets around four different stars. In the plot, more than 80% of the data points with Al/Si closest to 0 for each star actually overlap, so only the planets with higher Al/Si are fully and individually displayed. The values for the Earth (McDonough 2014) and Mars (Yoshizaki & McDonough 2020) are shown for reference, together with their frac-tionation lines (the gray dashed lines). The planetesimal formation time of 0.8 Myr is assumed here.
