Shaking and Tumbling: Short- and Long-Timescale Mechanisms for Resurfacing of Near-Earth Asteroid Surfaces from Planetary Tides and Predictions for the 2029 Earth Encounter by (99942) Apophis
R. -L. Ballouz, H. Agrusa, O. S. Barnouin +14
Spectral characterization of near-Earth asteroids (NEAs) has revealed a continuum of space-weathered states for the surfaces of S-complex NEAs, with Q-class NEAs, an S-complex subc…
Direct -body simulations of satellite formation around small asteroids: insights from DART's encounter with the Didymos system
Harrison F. Agrusa, Yun Zhang, Derek C. Richardson +18
We explore binary asteroid formation by spin-up and rotational disruption considering the NASA DART mission's encounter with the Didymos-Dimorphos binary, which was the first small…
An efficient numerical approach to modeling the effects of particle shape on rubble-pile dynamics
Julian C. Marohnic, Joseph V. DeMartini, Derek C. Richardson +2
We present an approach for the inclusion of non-spherical constituents in high-resolution N-body discrete element method (DEM) simulations. We use aggregates composed of bonded sph…
Constraining the final merger of contact binary(486958) Arrokoth with soft-sphere discrete element simulations
J. C. Marohnic, D. C. Richardson, W. B. McKinnon +8
The New Horizons mission has returned stunning images of the bilobate Kuiper belt object (486958) Arrokoth. It is a contact binary, formed from two intact and relatively undisturbe…
