The effects of the obliqueness and the strength of the external magnetic field on the propagation ion acoustic wave in a dusty plasma are investigated. The dispersion relation of the electrostatic wave is found to be modified by the Lorentz force. Th

A theoretical model is presented to show the existence, formation, and possible realization of large-amplitude dust-acoustic solitary potentials in electron-depleted hot dusty plasma with trapped ions. These nonlinear localized structures are self-co

We compute the expected luminosity function of GRBs in the context of the internal shock model. We assume that GRB central engines generate relativistic outflows characterized by the respective distributions of injected kinetic power Edot and contras

The expansion of a nonideal dusty plasma is investigated. The nonideal effects are modelled by a van der Waals equation of state, where the coefficients are calculated for each intergrain potential. It is found that the nonideal character of the expa

Using the Chapman–Enskog method, the calculations of the coefficients of self-diffusion D of neutral alkali–metal atoms in their respective parent gas as a function of the temperature T have been performed. These calculations are more accurate, s

The expansion of a dusty plasma into a vacuum with a variable charge is considered self-consistently. Due to the plasma spatial finitude, loss terms are introduced in fluid equations. Particles attachment also imposes that the Boltzmann distribution

The extended fluid analysis of the excitation of dust ion-acoustic waves (DIAWs) in a collisional dusty plasma [Merlino, IEEE Trans. Plasma Sci. 25, 60 (1997)] is reconsidered to include self-consistently the fluctuations in the charges of the dust g

Gravitational-electromagnetic entities “geons” are singularity-free solutions of the Einstein-Maxwell equations. These structures in cylindrical symmetry are considered here through the noncompactified Kaluza-Klein theory which describes geometri

A kinetic analysis of the excitation of dust BGK (Bernstein–Greene–Kruskal) modes in a noncollisional dusty plasma is presented. It is found that in the case where all the electrons are attached to the dust particles, consequent modifications in
