Example of the formation of a synthetic planetary system from initially 100 lunar-mass embryos in a typical protoplanetary disc with solar metallicity ([Fe/H] = 0.0). The epochs in time (in years) are shown in the top-left of the six panels. Solid points show (proto)planets with the semi-transparent part scaling with the radius. Grey crosses (fading in time) show the last position of protoplanets that were accreted by other more massive bodies. The colours of points represent the mass fraction of ice in the core. Horizontal black bars go from the periastron to the apoastron (i.e. represent orbital eccentricity). Lines show the growth tracks in the semi-major axis-mass plane.
