英文摘要:

Magnetic reconnection is an important universal plasma dissipation process that converts magnetic energy into plasma thermal and kinetic energy, and simultaneously changes the magnetic field topology. In this paper, we report the first observation of ener- getic electrons associated with asymmetric reconnection in the sheath of an interplanetary coronal mass ejection. The magnetic field shear angle was about 151°, implying guide-field reconnection. The width of the exhaust was about 8x104 km. The recon- nection rate was estimated as 0.044-0.08, which is consistent with fast reconnection theory and previous observations. We ob- served flux enhancements of energetic electrons with energy up to 400 keV in this reconnection exhaust. The region where ener- getic electron fluxes were enhanced is located at one pair of separatrices in the higher density hemisphere, We discuss these ob- servation results, and compare with previous observations and recent kinetic simulations.
