Search of Large Super-Fast Rotator between NEAs
Abstract
Asteroids of size larger than 0.15 km generally do not have periods smaller than 2.2 hours, a limit known as cohesionless spin-barrier. This barrier can be explained by the rubble-pile structure in which the asteroids are made up of collisional breakup fragments bound together by mutual gravitational force. The exceptions to this rule, called Large Super-Fast Rotators (LSFRs), are very few as 2001 OE84 and 2005 UW163. Preliminary results of some NEAs (Near Earth Asteroids) photometric observations are presented, we report the value of new rotation periods for these elusive asteroids.
