Spin-up of rubble-pile asteroids:Disruption,satellite formation,and equilibrium shapes
Asteroid, Dynamics Rotational dynamics Satellites,Dynamics
2015/12/25
We present results from numerical experiments testing the behavior of cohesionless gravitational aggregates experiencing a gradual increase of angular momentum. The test bodies used in these numerical...
Asteroids:equilibrium shapes of rotating gravitational aggregates
Asteroids shapes–Numerical simulations–Solar System evolution
2015/12/25
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 hydrodyna...

We present numerical experiments investigating the shape and spin limits of self-gravitating “perfect” rubble piles that consist of identical, smooth, rigid, spherical particles with configurable norm...
