Planetary systems produced in Model III with t_start = 0.5 Myr, S_peb = 10, and Rocky_peb = 0.1 cm from 50 simulations at the end of the simulations (50 Myr). Two panels are shown. Left-hand panel: stable systems (50%). Right-hand panel: unstable ones (50%). Planets are represented by dots. The sizes of the dots scale with mass as m^1∕3. The color ofeach dot indicates its ice-mass fraction.
