Effects of nonextensivity on the electronacoustic solitary structures in a magnetized electron−positron−ion plasma
Abstract
Obliquely propagating electronacoustic solitary waves (EASWs) in a magnetized electron−positron−ion plasma (containing nonextensive hot electrons and positrons, inertial cold electrons, and immobile positive ions) are precisely investigated by deriving the Zakharov–Kuznetsov equation. It is found that the basic features (viz. polarity, amplitude, width, phase speed, etc.) of the EASWs are significantly modified by the effects of the external magnetic field, obliqueness of the system, nonextensivity of hot positrons and electrons, ratio of the hot electron temperature to the hot positron temperature, and ratio of the cold electron number density to the hot positron number density. The findings of our results can be employed in understanding the localized electrostatic structures and the characteristics of EASWs in various astrophysical plasmas.

Ionacoustic (IA) solitary waves are investigated in a magnetized threecomponent plasma consisting of cold ions, isothermal hot electrons, and positrons. The basic set of fluid equations is reduced to the Korteweg de Vries equation using the standard reductive perturbation (multiplescale) technique. Theoretical and numerical analyses confirm significant effects of the presence of positrons and the dependence of the electron to positron temperature ratio on the amplitude and the width of IA solitary waves. It is shown that the rarefactive and compressive IA solitary excitations can propagate when the propagation angle {theta} satisfies 0{<=}{theta}<{pi}/2 and {pi}/2<{theta}{<=}{pi}, respectively. Also, it is remarkedmore »

Nonlinear ZakharovKuznetsov equation for obliquely propagating twodimensional ionacoustic solitary waves in a relativistic, rotating magnetized electronpositronion plasma
The purpose of this work is to investigate the linear and nonlinear properties of the ionacoustic waves (IAW), propagating obliquely to an external magnetic field in a weakly relativistic, rotating, and magnetized electronpositronion plasma. The ZakharovKuznetsov equation is derived by employing the reductive perturbation technique for this wave in the nonlinear regime. This equation admits the solitary wave solution. The amplitude and width of this solitary wave have been discussed with the effects of obliqueness, relativity, ion temperature, positron concentration, magnetic field, and rotation of the plasma and it is observed that for IAW these parameters affect the propagation propertiesmore » 
Oblique propagation of ionacoustic solitary waves in a magnetized electronpositronion plasma
The properties of obliquely propagating ionacoustic solitary waves in the presence of ambient magnetic field have been investigated theoretically in an electronpositronion nonthermal plasma. The plasma nonthermality is introduced via the qnonextensive distribution of electrons and positrons. The Kortewegde Vries (KdV) and modified KdV (mKdV) equations are derived by adopting reductive perturbation method. The solution of KdV and modified KdV equation, which describes the solitary wave characteristics in the long wavelength limit, is obtained by steady state approach. It is seen that the electron and positron nonextensivity and external magnetic field (obliqueness) have significant effects on the characteristics of solitarymore » 
Dustacoustic solitary structures in a magnetized dusty plasma with twotemperature nonextensive electrons
The nonlinear propagation of dustacoustic (DA) waves in an obliquely propagating magnetized dusty plasma, containing nonextensively distributed electrons of distinct temperatures (namely lower and higher temperature nonextensive electrons), negatively charged mobile dust grains, and Maxwellian ions, is rigorously studied and analyzed by deriving the ZakharovKuznetsov equation. It is found that the characteristics of the DA solitary waves (DASWs) are significantly modified by the external magnetic field, obliqueness of the system, nonextensivity of the electrons, electron temperatureratios, and the respective number densities of two species of electrons. The results obtained from this analysis can be employed in understanding and treating themore » 
Multidimensional instability of electronacoustic solitary waves in a magnetized plasma with vortexlike electron distribution
The basic features of obliquely propagating electronacoustic (EA) solitary waves and their multidimensional instability in a magnetized plasma containing cold electrons, hot electrons obeying a vortexlike distribution, and stationary ions have been theoretically investigated by the reductive perturbation method and smallk perturbation expansion technique. The combined effects of external magnetic field (obliqueness) and trapped electron distribution, which are found to significantly modify the basic properties (amplitude and width) of small but finiteamplitude EA solitary waves, are explicitly examined. It is also found that the instability criterion and the growth rate are significantly modified by the external magnetic field and themore »
