Small craters (less than one kilometer diameter) can be primary craters produced by impact
of interplanetary debris, or they can be secondary craters produced by fallback of high …

Collisions are the core agent of planet formation. In this work, we derive an analytic
description of the dynamical outcome for any collision between gravity-dominated bodies …

The resistance of planetesimals to collisional erosion changes dramatically during planet
formation. The transition between accretion and erosion from a collision is defined by the …

The outcome of collisions between small icy bodies, such as Kuiper belt objects, is poorly
understood and yet a critical component of the evolution of the trans-neptunian region. The …

This paper presents a series of experiments on high-velocity fracture of ice. Two types of
experimental results are examined: standard material characterization under compression …

This paper reviews the present status of the study of interstellar icy grains and formation of
the solar system from a point of view of condensation and sublimation of ices. The ices …

In this experimental and theoretical study, the impact of non-spherical and spherical ice
particles onto a solid surface is investigated. The impact velocity of the particles was varied …

The delivery dynamics of martian meteorites are examined by means of a direct numerical
simulation of their orbital evolution. The dynamics in the martian region are dominated by …

For several decades, most planetary researchers have regarded the impact crater
populations on solid-surfaced planets and smaller bodies as predominantly reflecting the …

Penetrator–ice plate impact subjected to dynamic loading constitutes many scientific
applications for ice, such as controlling ice disasters by penetrating the ice cover and then …
