Particle acceleration by relativistic expansion of magnetic arcades

  • Hiroyuki Takahashi (a1), Eiji Asano (a1) and Ryoji Matsumoto (a2)

Abstract

We carried out relativistic force free simulations and Particle In Cell (PIC) simulations of twist injection into the magnetic arcades emerging on the surface of a magnetar. As the magnetic energy is accumulated in the arcades, they expand self-similarly. In the arcades, a current sheet is formed and magnetic reconnection takes place. We also carried out 2-dimensional PIC simulations for the study of particle acceleration through magnetic reconnection. As a result, the energy spectrum of particles can be fitted by a power-law.
