Graphs and final architecture
Architecture: body mass vs orbit (log-log). Blue = ice-rich, tan = rocky, orange = gas giant.
Surface density (g/cm2): gas (blue) with gaps and decay, planetesimal sea (gold) being eaten; dashed = initial.
Number of bodies and heaviest body vs time; dashed line = gas dispersal.
Mass distribution: number of bodies per logarithmic mass bin (tan = rocky, blue = ice-rich, orange = gas giant).
Experiments
A. Snow-line isolation mass. Six isolated embryos, three inside and three outside the snow line, grown for 45 Myr and compared with the analytic isolation mass. B. Gap-opening mass vs viscosity. Self-check tests the model against closed forms.
