Investigating Local- and Global-scale Dust Redistribution on Comet 67P/Churyumov–Gerasimenko

open access: yesThe Planetary Science Journal
We use a 3D dynamical Monte Carlo model to simulate the trajectories of individual dust grains and map their redeposition across the surface of comet 67P/Churyumov–Gerasimenko.
