Abstract

Kinetic Alfvén waves (KAWs) have been studied in a low-β magnetized plasma, consisting of positively charged ions and two non-Maxwellian (kappa-distributed) electron populations. Linear and nonlinear analysis reveals the impact of suprathermal electrons on linear dispersion characteristics and on localized KAW modes (pulses). Super-Alfvénic speed negative potential structures are predicted via a Sagdeev-type method, whose characteristics are briefly discussed.
