| Research Abstract |
It is known that a high Mach number collisionless shock is often self-reforming, i.e., the shock front is cyclically formed and destroyed even though the upstream plasma parameters are steady. The self-reformation was originally found in numerical simulation studies, while its observational proof has not been established. In this study the basic features of the self-reformation is revealed by using numerical simulations. In particular we focus the phenomenon called reflected electron burst accompanied by the self-reformation and discuss how the characteristics of the self-reformation are transferred through it to a remote upstream region
