Strong reconnection electric fields in shock-driven turbulence

Turbulent magnetic reconnection in a quasi-parallel shock under parameters relevant to the Earth's bow is investigated by means of two-dimensional particle-in-cell simulation. The addressed aspects include electric field, rate, and electron ion outflow speeds. In transition region, many current sheets are generated shock-driven turbulence, electron-only where both ions electrons involved can occur those sheets. speed shows positive correlation with theoretical speed, which close local Alfvén strong convection field large outflow. As result, becomes much larger than standard magnetopause or magnetotail reconnection. that involves dynamics, outflows reach order 10 times X-line rest frame, leading same as An event observed magnetospheric multiscale mission downstream qualitatively similar simulation reaches approximately half supporting prediction.
