Recent numerical studies suggest that ‘rubble-pile’ asteroids (gravitationally bound aggregates of collisional debris) are common in the Solar System, and that self-gravitation may equal or exceed material cohesion for planetary bodies as small as several hundred metres. Because analytical scaling relations for impact cratering and disruption do not extend to this size regime, where gravity and material strength are both important, detailed simulations are needed to predict how small asteroids… 

Numerical simulations of asteroids modelled as gravitational aggregates with cohesion

Evidence is mounting that asteroids larger than a few hundred metres in diameter are gravitational aggregates of smaller, cohesive pieces. For example, images of 25143 Itokawa show a boulder-strewn

Effects of orbital ellipticity on collisional disruptions of rubble-pile asteroids

The behavior of debris ejected from asteroids after collisional disruptions has significant implications for asteroid evolution. Analytical approximations of the elliptic restricted three-body system

Catastrophic Disruptions Revisited

Abstract We use a smooth particle hydrodynamics method to simulate colliding rocky and icy bodies from centimeter scale to hundreds of kilometers in diameter in an effort to define self-consistently

Asteroid Interiors

Asteroids represent a geophysical frontier of considerable scientific importance, for these building blocks of planets preserve a compositional and mechanical record of the solar system’s origin.

How Many Rubble Piles Are in the Asteroid Belt

Abstract We have developed a new version of the code built by Campo Bagatin et al. (1994a, Planet. Space Sci. 42 , 1079–1092; 1994b, ibid. , 42 , 1099–1107) and Campo Bagatin (1998, Ph.D. thesis,

Direct N-body Simulations of Rubble Pile Collisions in Strong Tidal Fields: Applied to Saturn's F Ring

There is increasing evidence that many kilometer-sized bodies in the Solar System are piles of rubble bound together by gravity. We present results from a project to map the parameter space of

The moniker rubble pile is typically applied to all Solar System bodies >200 m and <∼10 km in diameter; in this size range, there is an abundance of evidence that nearly every object is bound

We use the smoothed particle hydrodynamics method to simulate catastrophic collisions on silicate bodies whose impact response is dominated by gravity rather than material strength. Encounter speeds

Mechanical and geological effects of impact cratering on Ida

Asteroids respond to impact stresses differently from either laboratory specimens or large planets. Gravity is typically so small that seismic disturbances of a few cm s−1can devastate unconsolidated
