Collisional growth efficiency of dust aggregates and its independence of the strength of interparticle rolling friction
Sota Arakawa, Hidekazu Tanaka, Eiichiro Kokubo
The pairwise collisional growth of dust aggregates consisting submicron-sized grains is the first step of the planet formation, and understanding the collisional behavior of dust a…
Fine-grained rim formation via kinetic dust aggregation in shock waves around evaporating icy planetesimals
Sota Arakawa, Hiroaki Kaneko, Taishi Nakamoto
Fine-grained rims (FGRs) are frequently found around chondrules in primitive chondrites. The remarkable feature of FGRs is their submicron-sized and non-porous nature. The typical…
On the crystallinity of silicate dust in evolving protoplanetary disks due to magnetically driven disk winds
Sota Arakawa, Yuji Matsumoto, Mitsuhiko Honda
We present a novel mechanism for the outward transport of crystalline dust particles: the outward radial drift of pebbles. The dust ring structure is frequently observed in protopl…
On the stickiness of CO and HO ice particles
Sota Arakawa, Sebastiaan Krijt
Laboratory experiments revealed that CO ice particles stick less efficiently than HO ice particles, and there is an order of magnitude difference in the threshold veloc…
Assessment of Cr isotopic heterogeneities of volatile-rich asteroids based on multiple planet formation models
Ryota Fukai, Sota Arakawa
Describing the comprehensive evolutionary scenario for asteroids is key to explaining the various physical processes of the solar system. Bulk-scale carbonaceous chondrites (CCs) p…
Thermal inertias of pebble-pile comet 67P/Churyumov-Gerasimenko
Sota Arakawa, Kazumasa Ohno
The Rosetta mission to comet 67P/Churyumov-Gerasimenko has provided new data to better understand what comets are made of. The weak tensile strength of the cometary surface materia…
