Existence of the kinetic Alfv,n solitons in a plasma with non-extensive electrons including complete ion nonlinearity

摘要

The existence of the shear Alfv,n solitons in a moderate beta plasma with non-extensive electrons including complete ion nonlinearity is investigated. The characteristic of super-Alfv,nic dip and hump type solitons, and the sub-Alfv,nic dip solitons depends on the electrons non-extensive parameters q. The effects of the q on the kinetic Alfv,n solitons can be explained from the effective electron temperature and the electron distribution in a potential field modified by the non-extensive distribution.
