Electronacoustic solitons in currentcarrying magnetized plasmas
Abstract
Nonlinear, finite amplitude electronacoustic waves in a current carrying magnetized collisionless plasma, with ion temperature much greater than the electron temperature, are found to be governed by a modified KdV equation. Using the method of inverse scattering, it is shown that this equation gives damped or growing solitons with tail formation on the reverse side. For a given solitonwidth, the rates of these processes increase as the angle between the propagation vector and the magnetic field decreases. But a change in the electron to ion temperature ratio affects only the velocity of the soliton.
