Аннотация:An electron-magnetohydrodynamic model is used
to simulate the structure of an electron scale current sheet
during early phase of collisionless magnetic reconnection.
The current sheet develops structures, viz. bifurcated, filamented
and triple-peak structures at different locations in
the current sheet. The reversal of the net out-of-plane electric
field seen by electrons bifurcates the current sheet in the
outflow regions, the individual peaks having scale sizes of a
few electron skin depths. Secondary instabilities of the bifurcated
CS lead to its filamentation in the outflow and separatrix
regions while triple-peak structures form at reconnection
sites. These structures have implications for the forthcoming
NASA/MMS mission designed to resolve electron space and
time scales in the magnetosphere.
