Driving Mechanism of Jets and Outflows in Star Formation Process
Masahiro N. Machida, Shu-ichiro Inutsuka, Tomoaki Matsumoto
The driving mechanism of jets and outflows in star formation process is studied using resistive MHD nested grid simulations. We calculated cloud evolution from the molecular cloud…

Stability of Toomre-Hayashi Disk
Tomoyuki Hanawa, Kazuya Saigo, Tomoaki Matsumoto
We investigate stability of Toomre-Hayashi model for a self-gravitating, rotating gas disk. The rotation velocity, , and sound speed, , are spatially constant i…

Fragmentation of a Magnetized Filamentary Molecular Cloud Rotating around its Axis
Tomoaki Matsumoto, Fumitaka Nakamura, Tomoyuki Hanawa
The dynamical instability of a self-gravitating magnetized filamentary cloud was investigated while taking account of rotation around its axis. The filamentary cloud of our model i…
