Finite amplitude ion-cyclotron and ion-acoustic waves solitons propagating obliquely in a magnetized warm-ion plasma are considered using exact ion dynamics quasi-neutrality. The effect of finite temperature is to decrease the soliton increase its width. behaviour amplitudes studied as function E0, where E0 slope potential profile at points equilibrium particle density.

Abstract Test-particle simulations are an important tool for magnetospheric and heliophysics research. In this paper, we present the Space Plasma Energetic Charged particle TRansport on Unstructured Meshes (SPECTRUM) software as a novel performing these types of in arbitrary astrophysical environments, specified either analytically or numerically (i.e., grid). We discuss benchmark SPECTRUM’s interface with meshed magnetohydrodynamic backgrounds, including output from Block Adaptive Tree...

A theoretical analysis of acoustic-like modes in a plasma consisting two kinds ions with different temperatures has been performed using fluid equations. The electrons are assumed to form dynamic neutralizing background, and their perturbation neglected – which is permissible for k 2 λ De ≫ 1. shows that an mode appears propagate as normal when the hotter ion concentration very large compared colder ions.

The transient response of nonlinear coupling between relatively high frequency magnetosonic wave (HMSW) and low (LMSW) in the overdense plasma has been presented this paper.

We present modeling of laser pulse compression and intensity enhancement during propagation in underdense plasma having relativistic intensity. Pulse duration shortens to less than 5 fs 11 times has been reported. Nonlinearity generates new frequency by self phase modulation which broadens the spectrum that turn duration. High pushes velocity electrons up limit modifies dielectric constant plasma. Modification refractive index profile causes focusing pulse. shortening happen accordance with...

Abstract Solar wind turbulence at large inertial scales is well known for decades and believed to consist of Alfvén cascade. At the order proton length, cascade excites kinetic wave, fast or whistler wave that carries energy smaller scales.

Inclusion this in makes them dispersive. In approach, dynamical...
