Electron beam-plasma interaction and electron-acoustic solitary waves in a plasma with suprathermal electrons
Ashkbiz Danehkar
Suprathermal electrons and inertial drifting electrons, so called electron beam, are crucial to the nonlinear dynamics of electrostatic solitary waves observed in several astrophys…
Electrostatic solitary waves in an electron-positron pair plasma with suprathermal electrons
Ashkbiz Danehkar
The nonlinear propagation of electrostatic solitary waves is studied in a collisionless electron-positron pair plasma consisting of adiabatic cool electrons, mobile cool positrons…
Propagation of Electron-Acoustic Waves in a Plasma with Suprathermal Electrons
Ashkbiz Danehkar
Electron-acoustic waves occur in space and laboratory plasmas where two distinct electron populations exist, namely cool and hot electrons. The observations revealed that the hot e…
Electron-acoustic solitons in an electron-beam plasma system with kappa-distributed electrons
A. Danehkar, I. Kourakis, M. A. Hellberg
We investigate the existence conditions and propagation properties of electron-acoustic solitary waves in a plasma consisting of an electron beam fluid, a cold electron fluid, and…
Effect of superthermality on nonlinear electrostatic modes in plasmas
S. Sultana, A. Danehkar, N. S. Saini +2
The nonlinear propagation of electron-acoustic solitary structures is investigated in a plasma containing kappa-distributed (superthermal) electrons. Different types of localized s…
