Dynamical Evolution of V-Shaped Collision Debris

Naoya Torii, Ryuki Hyodo

Catastrophic proto-satellite collisions do not produce massive Saturnian rings but instead drive debris to reaccrete near the original impact radius.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

catastrophic proto-satellite collisions do not produce massive Saturnian rings. Rather, the debris evolves toward reaccretion into a new generation of satellite-sized bodies near the impact radius.

C2weakest assumption

The assumption that the initial V-shaped distribution in the a-e plane persists long enough for inter-arm collisions to dominate evolution, combined with the specific fragmentation treatment in the N-body simulations accurately capturing real collisional physics without significant numerical artifacts.

C3one line summary

V-shaped collision debris from proto-satellites reaccretes near the original impact radius rather than forming massive rings due to dominant inter-arm collisions.
