Double layers in strong turbulent plasmas

On the basis of two magneto-fluid model for two time-scales, the double layer formation in strong turbulent plasma is examined; it is shown that double layer is a moving nonlinear entity in this case: soliton and wave-packet shock. It turns out that subsonic moving double layer is a double-double layer and might be cccounted as electric detonator in cosmic bodies; supersonic moving double layer possesses soliton pattern of shock type and it can be broken up into a single double layer within the bounds of possibility.
