Smoothed particle magnetohydrodynamics with a Riemann solver and the method of characteristics
Kazunari Iwasaki, Shu-ichiro Inutsuka
In this paper, we develop a new method for magnetohydrodynamics (MHD) using smoothed particle hydrodynamics (SPH). To describe MHD shocks accurately, the Godunov method is applied…
Alfven Wave Amplification and Self-Containment of Cosmic-Rays Escaping from a Supernova Remnant
Yutaka Fujita, Fumio Takahara, Yutaka Ohira +1
We study the escape of cosmic-ray (CR) protons accelerated at a supernova remnant (SNR) by numerically solving a diffusion-convection equation from the vicinity of the shock front…
Gravitational Fragmentation of Expanding Shells. II. Three-dimensional Simulations
Kazunari Iwasaki, Shu-ichiro Inutsuka, Toru Tsuribe
We investigate the gravitational fragmentation of expanding shells driven by HII regions using the three-dimensional Lagrangian simulation codes based on the Riemann solver, called…
Gravitational Fragmentation of Expanding Shells. I. Linear Analysis
Kazunari Iwasaki, Shu-ichiro Inutsuka, Toru Tsuribe
We perform a linear perturbation analysis of expanding shells driven by expansions of HII regions. The ambient gas is assumed to be uniform. As an unperturbed state, we develop a s…
