Example of the formation of a planetary system from initially 100 lunar-mass embryos in a high gas mass (initial mass 0.066 M_⊙), high metallicity ([Fe/H] = 0.23) disc. The initial mass of planetesimals is 432 M_⊕. The plot is analogous to Fig. 19, but the y-axis now extends to much higher masses, and the moments in time that are shown are different. At the end of the simulation at 20 Myr, this system contains one close-in sub-Neptunian planet, three giant planets, and a group of outer very low-mass planets.
