Insights on the Sun birth environment in the context of star-cluster formation in hub-filament systems
Doris Arzoumanian, Sota Arakawa, Masato I. N. Kobayashi +7
Cylindrical molecular filaments are observed to be the main sites of Sun-like star formation, while massive stars form in dense hubs, at the junction of multiple filaments. The rol…
Interpebble contact radius in a comet nucleus
Sota Arakawa, Daisuke Nishiura, Mikito Furuichi
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, ``pebble…
Igneous Rim Accretion on Chondrules in Low-Velocity Shock Waves
Yuji Matsumoto, Sota Arakawa
Shock wave heating is a leading candidate for the mechanisms of chondrule formation. This mechanism forms chondrules when the shock velocity is in a certain range. If the shock vel…
Threshold velocity for collisional growth of porous dust aggregates consisting of cohesive frictionless spheres
Sota Arakawa, Hidekazu Tanaka, Eiichiro Kokubo +2
Understanding the collisional outcomes of dust aggregates and dependence on material properties of the constituting particles is of great importance toward understanding planet for…
Rocky Planetesimal Formation via Fluffy Aggregates of Nanograins
Sota Arakawa, Taishi Nakamoto
Several pieces of evidence suggest that silicate grains in primitive meteorites are not interstellar grains but condensates formed in the early solar system. Moreover, the size dis…
