On the Rotations of M Asteroids
1982According to the theory of collisional evolution of asteroid rotations by Harris (1979) the densest objects should have the highest average spin rates. Since it is widely believed that M asteroids are of metallic composition, this theory predicts that they rotate more rapidly than the stony C or S objects. Harris and Burns (1979) found indications that

Asteroids: equilibrium shapes of rotating gravitational aggregates .
2011Many evidences lead us to think that a significant portion of asteroids are aggregates of boulders kept together by gravity, with little or no contribution from cohesive forces. The standard hydrodynamics results for a self-gravitating and rotating cohesionless body would impose it to stay close to one of the well-known equilibrium sequences of ...

Monitoring super-fast rotating asteroid candidates
IntroductionThe spin period is essential for asteroid studies: it underpins the determination of surface thermal properties (Delbo et al., 2015; Hung et al., 2022; Novaković et al., 2024), internal structures (Rozitis et al., 2014; Fodde & Ferrari), and modeling non-gravitational effects (Yarkovsky, YORP; Vokrouhlický et al., 2015; Fenucci & ...Bojan Novakovic, Pedro Gutiérrez

On the Slow Rotation of Asteroids
Icarus, 2002Abstract Asteroids with very slow rotation rates, up to 100 times slower than the mean for ordinary asteroids, are clearly a statistically distinct population from the rest. The cause of such slow rotation has remained a mystery since the discovery of the population about 20 years ago. The expected distribution of slow rotations for three-dimensional

Uniformly Rotating Bodies: Asteroid 433 Eros
2012The fundamental problem of orbital dynamics about small bodies is typified by the interaction of the spacecraft with a non-spherical body that is rotating uniformly in space. This was the problem presented to NASA’s Near Earth Asteroid Rendezvous (NEAR) mission when it had its rendezvous with asteroid 433 Eros.

Asteroid Pairs Formed by Rotational Fission
2010A population of small main-belt asteroid pairs (MBAs) residing on very similar heliocentric orbits have been found and studied recently (Vokrouhlicky and Nesvorny, Astron. J. 136: 280 2008 and Astron. J. 137: 111 2009, Pravec and Vokrouhlicky, Icarus 204: 580 2009).
