Study the behavior and evolution of disks of particles under the influence of planets in accretion is fascinating.
Something that would be interesting to do is to launch at low speed ( and outside of the disk but in the same plane) a planet with the mass of Jupiter toward the star simulating a stochastic migration and observe what effect it would cause the disk.
The disk would be re-aggregates after the passage of the giant planet that would allow new planets arose in the wake of the passage big body ? This would explain why we have extrasolar planets in systems where giant planets are close to the star due to migration processes?
