By performing N-body simulations, we investigated the fundamental processes of collisions
between dust aggregates composed of submicron-sized icy dust monomers. We examined …

The structure of dust aggregates affects many aspects of planet formation, such as the dust
collision outcome, opacity, and radiation field. The millimeter-wave scattering polarization in …

Understanding the collisional behavior of dust aggregates is essential in the context of
planet formation. It is known that low-velocity collisions of dust aggregates result in bouncing …

Understanding the collisional outcomes of dust aggregates and their dependence on the
material properties of the constituting particles is of great importance for understanding …

Context. Collisions between porous dust aggregates are crucial for the evolution of
protoplanetary disks. Aims. We study how the porosity, relative velocity, and impact …

High-precision isotopic measurements of meteorites revealed that they are classified into
non-carbonaceous (NC) and carbonaceous (CC) meteorites. One plausible scenario for …

The pairwise collisional growth of dust aggregates consisting of submicron-sized grains is
the first step of planet formation, and understanding the collisional behavior of dust …

We present a semi-analytic model for the growth, drift, desorption, and fragmentation of
millimeter-to meter-sized particles in protoplanetary disks. Fragmentation occurs where …

Collisions between aggregates with different histories and compositions are expected to be
commonplace in dynamically active protoplanetary discs. None the less, relatively little is …

In recent years, the gravitational collapse of pebble clumps in the early Solar system has
been regarded as a plausible scenario for the origin of comets. In this context,'pebbles' …
