A generalized energy-consistent finite difference scheme for 10-moment magnetohydrodynamics
Keita Akutagawa, Shinsuke Imada, Munehito Shoda
Pressure anisotropy and off-diagonal pressure stresses are ubiquitous and play important roles in collisionless/weakly collisional plasmas. The Chew-Goldberger-Low (CGL) MHD model…
Multi-hierarchy simulation of Riemann problem for reconnection exhausts
Keita Akutagawa, Shinsuke Imada, Munehito Shoda
Magnetic reconnection drives a wide range of astrophysical plasma phenomena, including solar flares, by converting magnetic energy into plasma energy through changes in magnetic fi…
Influence of kinetic effects in large-scale magnetic reconnection with multi-hierarchy simulation code KAMMUY
Keita Akutagawa, Shinsuke Imada, Munehito Shoda
Magnetic reconnection is a multiscale phenomenon where fluid- and particle-scale processes interact. The particle-in-cell (PIC) method, capable of resolving kinetic (particle-scale…
Can plasmoid-mediated reconnection occur in collisionless systems?
Keita Akutagawa, Shinsuke Imada, Munehito Shoda
Magnetic reconnection is a process that converts magnetic energy into plasma energy by changing the magnetic field line topology. The outstanding question is why the reconnection r…
