Parker-Jeans Instability of Gaseous Disks Including the Effect of Cosmic Rays
Takuhito Kuwabara, Chung-Ming Ko
We use linear analysis to examine the effect of cosmic rays (CRs) on the Parker-Jeans instability of magnetized self-gravitating gaseous disks. We adopt a slab equilibrium model in…

The Acceleration Mechanism of Resistive MHD Jets Launched from Accretion Disks
T. Kuwabara, K. Shibata, T. Kudoh +1
We analyzed the results of non-linear resistive magnetohydrodynamical (MHD) simulations of jet formation to study the acceleration mechanism of axisymmetric, resistive MHD jets. Th…

Nonlinear Parker Instability with the Effect of Cosmic-Ray Diffusion
Takuhito Kuwabara, Kenji Nakamura, C. M. Ko
We present the results of linear analysis and two-dimensional local magnetohydrodynamic (MHD) simulations of the Parker instability, including the effects of cosmic rays (CRs), in…
