Mach number and plasma beta dependence of the ion temperature perpendicular to the external magnetic field in the transition region of perpendicular collisionless shocks
Ryo Yamazaki, Ayato Shinoda, Takayuki Umeda +1
Ion temperature anisotropy is a common feature for (quasi-)perpendicular collisionless shocks. By using two-dimensional full particle simulations, it is shown, that the ion tempera…

Cross-scale coupling at a perpendicular collisionless shock
Takayuki Umeda, Masahiro Yamao, Ryo Yamazaki
A full particle simulation study is carried out on a perpendicular collisionless shock with a relatively low Alfven Mach number (M_A=5). In the present study, we have performed a t…
Full particle simulation of a perpendicular collisionless shock: A shock-rest-frame model
Takayuki Umeda, Ryo Yamazaki
