Parisi(2013) has shown that a dynamically cold disk would be required for the formationand evolution of planetesimalsof different sizes during all the planetary formation process at all locations in the disk. This is consistent with recentlaboratory experiments where the internal structure of carbonaceous chondrites implies that their parent objects hadnever collided at a speed higher than around 200-400 m/s (Beitz et al.2013). Motivated by these results, we investigate apossible scenario for the source of carbonaceous chondrites looking for low velocity collisions among their parent bodiescandidates within the framework of the Nice Model.
