The Effect of Poloidal Magnetic Field on Type I Planetary Migration: Significance of Magnetic Resonance

Takayuki Muto, Masahiro N. Machida, Shu-ichiro Inutsuka

We study the effect of poloidal magnetic field on type I planetary migration by linear perturbation analysis in the shearing-sheet approximation and the analytic results are compar…

Conditions for the Formation of First-Star Binaries

Masahiro N. Machida, Kazuyuki Omukai, Tomoaki Matsumoto +1

The fragmentation process of primordial-gas cores during prestellar collapse is studied using three-dimensional nested-grid hydrodynamics. Starting from the initial central number…

Formation Scenario for Wide and Close Binary Systems

Masahiro N. Machida, Kohji Tomisaka, Tomoaki Matsumoto +1

Fragmentation and binary formation processes are studied using three-dimensional resistive MHD nested grid simulations. Starting with a Bonnor-Ebert isothermal cloud rotating in a…

Evolutionary Conditions in the Dissipative MHD System Revisited

Tsuyoshi Inoue, Shu-ichiro Inutsuka

The evolutionary conditions for the dissipative continuous magnetohydrodynamic (MHD) shocks are studied. We modify Hada's approach in the stability analysis of the MHD shock waves.…

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…
