Conditions of structural transition for collisionless electrostatic shock
Minh Nhat Ly, Takayoshi Sano, Youichi Sakawa +1
Collisionless shock acceleration, which transfers localized particle energies to non-thermal energetic particles via electromagnetic potential, is ubiquitous in space plasma. We in…
Transonic Dislocation Propagation in Diamond
Kento Katagiri, Tatiana Pikuz, Lichao Fang +24
The motion of line defects (dislocations) has been studied for over 60 years but the maximum speed at which they can move is unresolved. Recent models and atomistic simulations pre…
Rotational Dependence of Large-scale Dynamo in Strongly-stratified Convection: What Causes It?
Youhei Masada, Takayoshi Sano
In a rigidly-rotating magnetohydrodynamic (MHD) system with convective turbulence, a large-scale dynamo, categorized as the -type, can be excited when the spin rate is large e…
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.…
Laser astrophysics experiment on the amplification of magnetic fields by shock-induced interfacial instabilities
Takayoshi Sano, Shohei Tamatani, Kazuki Matsuo +19
Laser experiments are becoming established as a new tool for astronomical research that complements observations and theoretical modeling. Localized strong magnetic fields have bee…
Alfven number for the Richtmyer-Meshkov instability in magnetized plasmas
Takayoshi Sano
Magnetohydrodynamical evolution of the Richtmyer-Meshkov instability (RMI) is investigated by two-dimensional MHD simulations. The RMI is suppressed by a strong magnetic field, whe…
