Summary

Flux transfer events (FTEs) observed at the dayside magnetopause are believed to be caused by magnetic reconnection. Satellite observations of FTEs have shown the presence of particle heat flux and intense plasma waves. The particle heat flux and plasma waves associated with the magnetic reconnection processes at the dayside magnetopause are studied by using $$2{1 \over 2}$$ -dimensional electromagnetic particle simulations. It is observed in the simulations that superthermal particles are generated, leading to the presence of particle heat flux. Intense plasma waves are also observed. Typical power spectra of fluctuating magnetic and electric fields are found to be $$P_{B_z } \sim fˆ{ - 3.8} $$ and $$P_E \sim fˆ{ - 1.8}$$, respectively, where ƒ is the frequency. For a symmetric magnetic field configuration, both multiple X line reconnection (MXR) and single X line reconnection (SXR) processes lead to a simultaneous bipolar FTE signature on both sides of the current sheet; whereas for an asymmetric magnetic field configuration, MXR again generates the simultaneous FTE signature on both sides of the current sheet, however, SXR can produce the FTE signature only on the weak magnetic field side.
