Firehose instability in space plasmas with bi-kappa distributions
Context. The existence of suprathermal charged particle populations in space plasma is frequently confirmed by interplanetary missions. In general, the velocity distribution functions are anisotropic, field aligned (gyrotropic) with two temperatures, parallel (T‖) and perpendicular (T⊥) to the ambient magnetic field B0. Aims. Here, the dispersion properties of the firehose instability, which re...
متن کاملModulational instability of dust ion acoustic waves in astrophysical dusty plasmas with non thermal electrons
Propagation of dust ion acoustic waves in plasmas composed of nonthermal distributed electrons and stationary dust particles is investigated. Nonlinear Schrdinger equation is derived to describe small amplitude waves, using the reduction perturbation technique. Modulation instability of dust ion acoustic waves is analysed for this system. Parametric investigation indicates that growth rate of...
متن کاملStopping of Directed Energetic Electrons in High-Temperature Hydrogenic Plasmas
LLE Review, Volume 98 97 A basic problem in plasma physics is the interaction and energy loss of energetic charged particles in plasmas.14 This problem has traditionally focused on ions (i.e., protons, alphas, etc.), either in the context of heating and/or ignition in, for example, inertial confinement fusion (ICF)36 or the use of these particles for diagnosing implosion dynamics.7 More recen...
متن کاملStopping of directed energetic electrons in high-temperature hydrogenic plasmas.
From fundamental principles, the interaction of directed energetic electrons with a high-temperature hydrogenic plasma is analytically modeled. The randomizing effect of scattering off both plasma ions and electrons is treated from a unified point of view. For electron energies less than 3 MeV , electron scattering is equally important. The net effect of multiple scattering is to reduce the pen...
متن کاملInvestigation of Dust-Ion Acoustic Waves in a Magnetized Collisional Dusty Plasma with Kappa Distribution Function for Electrons
The propagation of arbitrary amplitude dust ion acoustic waves (DIAWs) in a magnetized collisional dusty plasma including hot electrons, with kappa velocity distribution for electrons, warm ions and dust particles has been studied. In the presence of immobile massive dust particulates, DIAWs have been investigated through the Sagdeev pseudo-potential method. It is demonstrated that the amplitud...
