The abundance of asteroids having unusually large angular momenta of rotation in the diameter range 200 - 300 km implies that, if these angular momenta have a collisional origin, the asteroid population was of the order of a few times the present one at the time when the orbits were stirred up and the disruptive collisional process begun. The meaning of this result and the issue of the collisional vs. "primordial" origin of the currently observed asteroid rotations are shortly discussed.

Abstract
The abundance of asteroids having unusually large angular momenta of rotation in the diameter range 200 - 300 km implies that, if these angular momenta have a collisional origin, the asteroid population was of the order of a few times the present one at the time when the orbits were stirred up and the disruptive collisional process begun. The meaning of this result and the issue of the collisional vs. "primordial" origin of the currently observed asteroid rotations are shortly discussed.File in questo prodotto:
