A simpler method is used to obtain differential equations producing ion acoustic solitary waves and double layers (DLs) in a an unmagnetized plasma. The electrons are assumed to follow Cairns-Tsallis and Kappa distribution functions while the ions ar

Physical mechanisms are discussed for the excitation of ion-acoustic waves (IAWs) by field-aligned shear flow of ions and parallel current produced by electrons in the upper ionospheric oxygen hydrogen plasma within auroral latitudes. Theoretical mod

Using a kinetic theoretical approach, the characteristics of ion acoustic waves (IAWs) have been studied in a plasma whose electron and ion velocity distributions are modeled by a three dimensional q- nonextensive distribution function. It is found t

The impact of electron exchange-correlation term on the linear and nonlinear quantum ion (QIA) acoustic drift waves in a highly degenerate plasma is investigated. An analytical approach is employed to derive the differential equation which is later o

Kinetic theory of electron acoustic waves (EAWs) in the presence of wave angular momentum has been derived to study the effect of wave angular momentum on the propagation of EAWs in a non-Maxwellian plasma. Both types of electrons (hot and cool) are

Effects of non-Maxwellian electron densities on the low frequency electrostatic waves and instabilities are pointed out in a bi-ion plasma having field-aligned shear flow. Several different electron densities are used and formation of nonlinear stati

The nonlinear propagation of ion-acoustic waves is studied in an unmagnetized collissionless electronegative plasma, whose constituents are the inertial warm positive/negative ions and q-distributed nonextensive electrons. The latter have strong impa
