Abstract The Double Asteroid Redirection Test (DART) spacecraft will impact into the
asteroid Dimorphos on 2022 September 26 as a test of the kinetic impactor technique for …

With meshfree and fully Lagrangian features of particle methods, smoothed particle
hydrodynamics (SPH) is suitable to achieve high-accurate simulations of multiphase flows …

The question whether the interaction of a circumbinary disc with the central binary system
leads to a shrinking or to an expansion of the binary orbit has attracted considerable interest …

Crush curves are of fundamental importance to numerical modeling of small and porous
astrophysical bodies. The empirical literature often measures them for silica grains, and …

Although it is accepted that perfect-merging is not a realistic outcome of collisions, some
researchers state that perfect-merging simulations can still be considered as quantitatively …

One common approach for solving collisions between protoplanets in simulations of planet
formation is to employ analytical scaling laws. The most widely used one was developed by …

The last phase of the formation of rocky planets is dominated by collisions among Moon-to
Mars-sized planetary embryos. Simulations of this phase need to handle the difficulty of …

Fast and accurate treatment of collisions in the context of modern N-body planet formation
simulations remains a challenging task due to inherently complex collision processes. We …
