Numerical Simulations of Collisional Disruption of Rotating Gravitational Aggregates: Dependence on Material Properties
Ronald-Louis Ballouz, Derek C Richardson, Patrick Michel +2
Our knowledge of the strengths of small bodies in the Solar System is limited by our poor understanding of their internal structures, and this, in turn, clouds our understanding of…
The Design Reference Asteroid for the OSIRIS-REx Mission Target (101955) Bennu
Carl W. Hergenrother, Maria Antonietta Barucci, Olivier Barnouin +23
The Design Reference Asteroid (DRA) is a compilation of all that is known about the OSIRIS-REx mission target, asteroid (101955) Bennu. It contains our best knowledge of the proper…
Low-speed Impact Simulations into Regolith in Support of Asteroid Sampling Mechanism Design I.: Comparison with 1-g Experiments
Stephen R. Schwartz, Patrick Michel, Derek C. Richardson +1
This study is carried out in the framework of sample-return missions to asteroids that use a low-speed projectile as the primary component of its sampling mechanism (e.g., JAXA's H…
Numerical predictions of surface effects during the 2029 close approach of asteroid 99942 Apophis
Yang Yu, Derek C. Richardson, Patrick Michel +2
Asteroid (99942) Apophis' close approach in 2029 will be one of the most significant small-body encounter events in the near future and offers a good opportunity for in situ explor…
The Brazil-nut effect and its application to asteroids
Soko Matsumura, Derek C. Richardson, Patrick Michel +2
Out of the handful of asteroids that have been imaged, some have distributions of blocks that are not easily explained. In this paper, we investigate the possibility that seismic s…
Rotation-Dependent Catastrophic Disruption of Gravitational Aggregates
Ronald-Louis Ballouz, Derek C. Richardson, Patrick Michel +1
We carry out a systematic exploration of the effect of pre-impact rotation on the outcomes of low-speed collisions between planetesimals modeled as gravitational aggregates. We use…
