A short note on reconstruction variables in shock capturing schemes for magnetohydrodynamics
Takahiro Miyoshi, Takashi Minoshima
We propose a set of quick and easy approximate characteristic variables for higher-order reconstructions of shock capturing schemes for magnetohydrodynamics (MHD). Numerical experi…
Plasmoid-dominated Turbulent Reconnection in a Low Plasma
Seiji Zenitani, Takahiro Miyoshi
Properties of plasmoid-dominated turbulent reconnection in a low- background plasma are investigated by resistive magnetohydrodynamic (MHD) simulations. In the …
A Multistate Low-dissipation Advection Upstream Splitting Method for Ideal Magnetohydrodynamics
Takashi Minoshima, Keiichi Kitamura, Takahiro Miyoshi
We develop a new numerical scheme for ideal magnetohydrodynamic (MHD) simulations, which is robust against one- and multi-dimensional shocks, and is accurate for low Mach number fl…
A Magnetohydrodynamic Relaxation Method for Non-Force-Free Magnetic Field in Magnetohydrostatic Equilibrium
Takahiro Miyoshi, Kanya Kusano, Satoshi Inoue
A nonlinear force-free field (NLFFF) extrapolation is widely used to reconstruct the three-dimensional magnetic field in the solar corona from the observed photospheric magnetic fi…
A new HLLD Riemann solver with Boris correction for reducing Alfvén speed
Tomoaki Matsumoto, Takahiro Miyoshi, Shinsuke Takasao
A new Riemann solver is presented for the ideal magnetohydrodynamics (MHD) equations with the so-called Boris correction. The Boris correction is applied to reduce wave speeds, avo…
Magnetohydrodynamic structure of a plasmoid in fast reconnection in low-beta plasmas: Shock-shock interactions
Seiji Zenitani
The shock structure of a plasmoid in magnetic reconnection in low-beta plasmas is investigated by two-dimensional magnetohydrodynamic simulations. Using a high-accuracy code with u…
