Direct Simulations of Particle Acceleration in Fluctuating Electromagnetic Field across a Shock
Takayuki Muranushi, Shu-ichiro Inutsuka
We simulate the acceleration processes of collisionless particles in a shock structure with magnetohydrodynamical (MHD) fluctuations. The electromagnetic field is represented as a…
The Role of Ambipolar Diffusion in the Formation Process of Moderately Magnetized Diffuse Clouds
Tsuyoshi Inoue, Shu-ichiro Inutsuka, Hiroshi Koyama
We investigate the dynamical condensation process in a magnetized thermally bistable medium. We perform one-dimensional two fluid numerical simulations that describe the neutral an…
Synthetic Observations of Carbon Lines of Turbulent Flows in Diffuse Multiphase Interstellar Medium
M. Yamada, H. Koyama, K. Omukai +1
We examine observational characteristics of multi-phase turbulent flows in the diffuse interstellar medium (ISM) using a synthetic radiation field of atomic and molecular lines. We…
Nonlinear Development of Thermal Instability without External Forcing
Hiroshi Koyama, Shu-ichiro Inutsuka
Supersonic turbulent motions are the remarkable properties of interstellar medium. Previous numerical simulations have demonstrated that the thermal instability in a shock-compress…
Structure and Stability of Phase Transition Layers in the Interstellar Medium
Tsuyoshi Inoue, Shu-ichiro Inutsuka, Hiroshi Koyama
We analyze the structure and stability of the transition layer (or front) that connects the cold neutral medium and warm neutral medium in the plane-parallel geometry. Such fronts…
How Long Can Tiny HI Clouds Survive?
Masahiro Nagashima, Shu-ichiro Inutsuka, Hiroshi Koyama
We estimate the evaporation timescale for spherical HI clouds consisting of the cold neutral medium surrounded by the warm neutral medium. We focus on clouds smaller than 1pc, whic…
