Impact of MHD disk wind on early evolutionary stage of protoplanetary disk and dust growth
Yoshihiro Kawasaki, Masahiro N. Machida
We perform one-dimensional protoplanetary disk evolution calculations to investigate the impact of the magnetohydrodynamic (MHD) disk wind on disk evolution and dust particle growt…
Ring Gap Structure around Class I Protostar WL 17
Ayumu Shoshi, Naoto Harada, Kazuki Tokuda +7
WL 17 is a Class I object and was considered to have a ring-hole structure. We analyzed the structure around WL 17 to investigate the detailed properties of WL 17. We used ALMA arc…
Impact of turbulence intensity and fragmentation velocity on dust particle size evolution and non-ideal magnetohydrodynamics effects
Yoshihiro Kawasaki, Masahiro N. Machida
We investigate the influence of dust particle size evolution on non-ideal magnetohydrodynamic effects during the collapsing phase of star-forming cores, taking both the turbulence…
Implementation of dust particles in three-dimensional magnetohydrodynamics simulation: Dust dynamics in a collapsing cloud core
Shunta Koga, Yoshihiro Kawasaki, Masahiro N. Machida
The aim of this study is to examine dust dynamics on a large scale and investigate the coupling of dust with gas fluid in the star formation process. We propose a method for calcul…
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…
Growth of Magnetorotational Instability in Circumstellar Disks around Class 0 Protostars
Yoshihiro Kawasaki, Shunta Koga, Masahiro N. Machida
We investigate the possibility of the growth of magnetorotational instability (MRI) in disks around Class 0 protostars. We construct a disk model and calculate the chemical reactio…
