Smoothed Particle Hydrodynamics in pkdgrav3 for Shock Physics Simulations. II. Shear Strength

Thomas Meier, Christian Reinhardt, Martin Jutzi +2

Material strength effects have been recently shown to be significant in giant impacts even at scales of planetary collisions. Despite this, their effects are often neglected in num…

Recent advances in modelling of global-scale collisions using smoothed particle hydrodynamics

Christian Reinhardt, Sabina D. Raducan, Thomas Meier +3

Impacts play a fundamental role in shaping the physical and chemical properties of the objects in our Solar System. Given the challenges in replicating such collisions through labo…

Experimental evidence for granular shear-flow instability in the Epstein regime

Holly L. Capelo, Jean-David Bodénan, Martin Jutzi +7

Stability analysis of two-fluid protoplanetary disc models has enriched our understanding of how solids can grow into larger bodies called planetesimals. Dust particles entrained i…

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…

Satellite formation around the largest asteroids

Kevin J. Walsh, Ronald-Louis Ballouz, Harrison F. Agrusa +3

Satellites around large asteroids are preferentially found among those with the most rapid rotation and elongated shape. The taxonomic statistics are similarly skewed; in total, 13…
