Typical time scale of coalescence at r=0.04 AU becomes 58k year.
These are the first generation planets.

内縁軌道でのスリングショット

Slingshot brings planets outer and inner parts of the disk.
Two Jupiters, at r=0.04AU, can slingshot up to Neptune mass. Many smaller planets are shot inward and outward. The eccentricity e and the orbital inclination i reduce. Relatively heavier planets shot outside the disk may form stray planets(2%). Many lighter blobs shot outside the disk may form belt structures.
