Oxygen Isotope Exchange Between Molten Silicate Spherules and Ambient Water Vapor with Nonzero Relative Velocity: Implication for Chondrule Formation Environment
Sota Arakawa, Daiki Yamamoto, Takayuki Ushikubo +4
Oxygen isotope compositions of chondrules reflect the environment of chondrule formation and its spatial and temporal variations. Here, we present a theoretical model of oxygen iso…

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…
