  author={Charles El Mir and KT Ramesh and Derek C. Richardson},
Abstract We present a hybrid approach for simulating hypervelocity impacts onto asteroids. The overall system response is separated into two stages based on their different characteristic timescales. First, the short-timescale fragmentation phase is simulated using a modified version of the Tonge–Ramesh material model implemented in a Material Point Method framework. Then, a consistent hand-off to an N -body gravity code is formulated to execute the long-timescale gravitational reaccumulation… Expand

Merging Criteria for Planetesimal Collisions
In the standard scenario of planet formation, terrestrial planets, ice giants, and cores of gas giants are formed by the accumulation of planetesimals. However, there are few N-body simulationExpand
Optimization and decision-making framework for multi-staged asteroid deflection campaigns under epistemic uncertainties
Case scenarios targeting Apophis and Bennu substantiate the utility of the framework in optimizing different deflection campaign architectures and making decisions amongst them via newly proposed visualization methods. Expand
New HST data and modeling reveal a massive planetesimal collision around Fomalhaut
It is found that Fomalhaut b has faded in brightness and grown in extent, with motion consistent with an escaping orbit, and suggestions that the source is a dispersing cloud of dust, produced by a massive collision between two planetesimals in an extrasolar planetary system are confirmed. Expand
