Primary Rotations of Paired Asteroids

2009
A population of small main-belt asteroids residing on closely similar orbits was revealed by Vokrouhlicky and Nesvorny (2008, Astron. J. 136, 280-290). We have estimated statistical significances of individual pairs (Pravec and Vokrouhlicky 2009, Icarus, in press) and started a photometry observing program to characterize their spin properties ...

Rotational fission of contact binary asteroids

Icarus, 2007
The energetics and dynamics of contact binary asteroids as they approach and pass the rotational fission limit is studied. We presume that the asteroids are subject to an external torque, such as from the YORP effect, that increases their angular momentum.

Asteroid Rotational Disruption Optimization

Rotational disruption of asteroids is a crucial dynamical phenomenon in astrophysics. It occurs when an asteroid accelerates its rotation or increases its angular momentum, causing it to break apart or fragment due to its own gravity and material strength being unable to maintain its overall structure.

On the Rotations of M Asteroids

1982
According 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 .

2011
Many 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 & ...
