A study of solar energetic particle transport on 30 March 2022 using multi-spacecraft data assimilation
Takashi Minoshima, Yoshizumi Miyoshi, Go Murakami +7
We analyze a unique solar energetic particle event observed simultaneously by the BepiColombo and STEREO-A spacecraft on March 30, 2022. The two spacecraft at heliocentric distance…
A high-order weighted positive and flux conservative method for the Vlasov equation
Takashi Minoshima, Yosuke Matsumoto
We present a high-order conservative, positivity-preserving, and non-oscillatory scheme for solving the Vlasov equation. The scheme attains formal fifth-order accuracy through a co…
Quasi all-speed schemes for magnetohydrodynamic flows in a wide range of Mach numbers
Takashi Minoshima
We present novel numerical schemes for ideal magnetohydrodynamic (MHD) simulations aimed at enhancing stability against numerical shock instability and improving the accuracy of lo…
Optab: Public code for generating gas opacity tables for radiation hydrodynamics simulations
Shigenobu Hirose, Peter Hauschildt, Takashi Minoshima +2
We have developed a public code, Optab, that outputs Rosseland, Planck, and two-temperature Planck mean gas opacity tables for radiation hydrodynamics simulations in astrophysics.…
A low-dissipation HLLD approximate Riemann solver for a very wide range of Mach numbers
Takashi Minoshima, Takahiro Miyoshi
We propose a new Harten-Lax-van Leer discontinuities (HLLD) approximate Riemann solver to improve the stability of shocks and the accuracy of low-speed flows in multidimensional ma…
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…
