Catastrophic tidal disruption of heterogeneous rubble piles: a tale of two regimes
John Wimarsson, Eric Frizzell, Martin Jutzi +1
The way a rubble-pile body deforms or disrupts under the influence of tidal forces can be directly tied to its internal strength and configuration. Computational modelling of such…
Dynamical evolution and surface accretion of DART impact ejecta in the (65803) Didymos system
Xiaoyu Fu, Nicolo Stronati, Stefania Soldini +6
The DART spacecraft impacted Dimorphos, the small moonlet of Didymos binary system, on 26 September 2022. The impact ejected dust, fragments, and boulders into the near-binary envi…
The diverse shapes of binary asteroid satellites born from sub-escape-velocity moonlet mergers
John Wimarsson, Fabio Ferrari, Martin Jutzi
Recent direct observations of atypically shaped rubble-pile satellites of sub-km asteroids in form of the spherically oblate Dimorphos and bilobate Selam challenge classical binary…
Meteoroid stream identification with HDBSCAN unsupervised clustering algorithm
Eloy Peña-Asensio, Fabio Ferrari
Accurate identification of meteoroid streams is central to understanding their origins and evolution. However, overlapping clusters and background noise hinder classification, an i…
