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…
Tidal resurfacing model for (99942) Apophis during the 2029 close approach with Earth
Y. Kim, J. V. DeMartini, D. C. Richardson +1
We numerically investigate tidally induced surface refreshing on Apophis during its close approach with Earth within a perigee distance of 5.96 Earth radii on April 13, 2029. We im…
