DOI: 10.1002/ctpp.202000225
Abstract: We used a new distribution of electrons in a two‐component magnetized plasma to study the non‐linear ion‐acoustic solitary structures. The distribution called “Cairns–Gurevich distribution” describes simultaneously the evolution of the energetic electrons and those trapped… read more here.
