Figure 2: Evolution of a system initially containing a disk with a mass equal to 0.05 times that of the central body. The central body is shown in yellow, and the solid green line, the planet’s Roche limit. Isolated disk particles are displayed as black dots, while particles gravitationally bound into a satellite are colour-coded according to the satellite’s mass.
