- 論文の詳細を見る
Electron acceleration caused by small pulses in oblique shock waves in a reversed external magnetic field is studied with theory and particle simulations. Simulations show that after a shock wave has passed a neutral sheet, across which the external magnetic field is reversed, a new density pulse is produced in front of the original shock wave. This pulse quickly evolves into a shock wave with the magnetic polarity opposite to that of the original shock wave. In this secondary shock wave, two types of small pulses are generated. One is compressive, and the other is field reversed. In these small pulses, electron acceleration to ultrarelativistic energies is observed. A theoretical analysis is made on the electron acceleration in field-reversed small pulses that propagate obliquely to a magnetic field. It is confirmed that the simulation results are consistent with the theoretical predictions.
