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… Expand
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-strewnExpand

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 systemExpand
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-consistentlyExpand
The feasibility of using large impact to destroy a dangerous asteroid
Abstract Some physical aspects of high velocity ( >30 km / s ) collisions involving an asteroid or comet nucleus are discussed. Impacts by both meteoroids and massive artificial objects areExpand
Full numerical simulations of catastrophic small body collisions
Abstract The outcome of collisions between small icy bodies, such as Kuiper belt objects, is poorly understood and yet a critical component of the evolution of the trans-neptunian region. TheExpand
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.Expand
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,Expand
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 ofExpand
1620 Geographos and 433 Eros: Shaped by Planetary Tides
Until recently, most asteroids were thought to be solid bodies whose shapes were determined largely by collisions with other asteroids. Recent work by Burns and others has shown that many asteroidsExpand


Catastrophic Impacts on Gravity Dominated Asteroids
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 speedsExpand
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 unconsolidatedExpand
On the fragmentation of asteroids and planetary satellites
Abstract Theories of collisional fragmentation are highly speculative. Most of our knowledge of such events is based on experimental results. Unfortunately, due to practical constraints, theExpand

Abstract The formation of kilometer-size craters on asteroids is qualitatively different from the formation of meter-size (laboratory- and weapons-scale) craters on Earth. A numerical hydrocode modelExpand
