Abstract

By using the Sagdeev pseudopotential method, solitary kinetic Alfvén waves (SKAW) are studied in a low-β plasma, taking into account the electron inertia and ion temperature. Solitary wave solutions, and the electric and magnetic fields, are obtained using the knowledge of the pseudopotential analysis in plasma dynamics. It is found that both hump and dip solitons exist for SKAWs, conforming to the results of Freja scientific satellite observations in space.
