The Material Point Method (MPM) for simulating hypervelocity impact on asteroids
Xiaoran Yan, Patrick Michel, Ruichen Ni +2
Shock-physics numerical codes are essential tools for describing the short but extreme fragmentation stage of the hypervelocity impact process on asteroids. However, accurately rep…
High-Speed Boulders and the Debris Field in DART Ejecta
Tony L. Farnham, Jessica M. Sunshine, Masatoshi Hirabayashi +44
On 26 September 2022 the Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the moon of the near-Earth asteroid 65803 Didymos, in a full-scale demonstratio…
Secondary impact debris in the Didymos system: what could be observed by Hera?
Krzysztof Langner, Elena Martellato, Robert Luther +2
We investigate the effects of low--velocity impacts of rocks and boulders, originally released after the DART impact, on the surface of Didymos and the dynamics of dust particles r…
Physical properties of asteroid Dimorphos as derived from the DART impact
S. D. Raducan, M. Jutzi, A. F. Cheng +39
On September 26, 2022, NASA's Double Asteroid Redirection Test (DART) mission successfully impacted Dimorphos, the natural satellite of the binary near-Earth asteroid (65803) Didym…
Ejecta from the DART-produced active asteroid Dimorphos
Jian-Yang Li, Masatoshi Hirabayashi, Tony L. Farnham +61
Some active asteroids have been proposed to be the result of impact events. Because active asteroids are generally discovered serendipitously only after their tail formation, the p…
Predictions for the Dynamical States of the Didymos System before and after the Planned DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +33
NASA's Double Asteroid Redirection Test (DART) spacecraft is planned to impact the natural satellite of (65803) Didymos, Dimorphos, around 23:14 UTC on 26 September 2022, causing a…
