Dust Motion and Possibility of Dust Growth in a Growing Circumstellar Disk

Shunta Koga, Masahiro N. Machida

We calculate the evolution of a star-forming cloud core using a three-dimensional resistive magnetohydrodynamics simulation, treating dust grains as Lagrangian particles, to invest…

Dust coagulation and fragmentation in a collapsing cloud core and their influence on non-ideal magnetohydrodynamic effects

Yoshihiro Kawasaki, Shunta Koga, Masahiro N. Machida

We determine the time evolution of the dust particle size distribution during the collapse of a cloud core, accounting for both dust coagulation and dust fragmentation, to investig…
