Mechanism of Magnetic Flux Loss in Molecular Clouds
Takenori Nakano, Ryoichi Nishi, Toyoharu Umebayashi
We investigate the detailed processes working in the drift of magnetic fields in molecular clouds. To the frictional force, whereby the magnetic force is transmitted to neutral mol…
Magnetorotational Instability in Protoplanetary Disks. II. Ionization State and Unstable Regions
Takayoshi Sano, Shoken M. Miyama, Toyoharu Umebayashi +1
We investigate where in protoplanetary disks magnetorotational instability operates, which can cause angular momentum transport in the disks. We investigate the spatial distributio…
Evolution of Molecular Abundance in Protoplanetary Disks
Y. Aikawa, T. Umebayashi, T. Nakano +1
We investigate the evolution of molecular abundance in quiescent protoplanetary disks which are presumed to be around weak-line T Tauri stars. In the region of surface density less…
