[31] Apart from the well-known Lorentz force creating plasma fluid rotation, Coriolis force is also suggested [32] to be of importance in astrophysical environments. Both theoretical and experimental investigations reveal the fact that, no matter how weak the Coriolis force might be, it can lead to interesting phenomena in astrophysical environments.…”

The linear and non-linear dynamics of ion acoustic waves are investigated in three-component magnetized plasma consisting of cold inertial ions and non-thermal electrons and positrons. The non-thermal components are modelled by the hybrid distribution, representing the combination of two (kappa and Cairn's) non-thermal distributions. The relevant processes, including the slow rotation of plasma along the magnetic field axis and collision between ions and neutrals, are taken into consideration. It is shown that the non-linear dynamics of the considered system are governed by the Zakharov-Kuznetsov equation in modified form. In the general dissipation regime, the effects of the two non-thermal distributions on the solitary waves are compared. The effects of other plasma parameters, such as collisional and rotational frequency, are also discussed in detail.

“…In the limit k → ∞ [34,35] the kappa distribution function reduces to the well-known Maxwellian Boltzmann distribution. Recently, a numerous investigations have been made by many authors on ion-acoustic solitary waves (IASWs) with single-temperature superthermal (kappa distributed) electrons [36][37][38]. Schippers et al [39] have combined a hot and a cold electron component, while both electrons are kappa distributed and found a best fit for the electron velocity distribution.…”

The heavy ion acoustic solitary waves (HIASWs) in a magnetized, collisionless, three component space plasma system in the presence of dynamical heavy particles and bi-kappa distributed two distinct temperature of electrons has been carried out. The Korteweg-de Vries (K-dV), the modified K-dV (mK-dV), and the further mK-dV (fmK-dV) equations are derived by employing the well known reductive perturbation method. The basic features of HIASWs (speed, amplitude, width etc.) are found to be significantly modified by the effects of number density of plasma species, superthermal electrons with two distinct temperatures and the magnetic field (obliqueness). The K-dV and fm-KdV solitons exhibit both compressive and rarefactive structures, whereas the mK-dV solitons support only compressive structures. In order to trace the vicinity of the critical heavy ion density, neither the magnetized KdV nor magnetized mKdV equation is suitable for describing the HIASWs. Therefore, we have considered a higher order nonlinearity to describe the solitary profiles by deriving fmK-dV equation. The implication of our results in some space and laboratory plasma situations are concisely discussed.

The basic properties of dust-ion-acoustic (DIA) shock waves in an unmagnetized dusty plasma (containing inertial ions, kappa distributed electrons with two distinct temperatures, and negatively charged immobile dust grains) are investigated both numerically and analytically. The hydrodynamic equation for inertial ions has been used to derive the Burgers equation. The effects of superthermal bi-kappa electrons and ion kinematic viscosity, which are found to modify the basic features of DIA shock waves significantly, are briefly discussed.
