In a previous paper, sufficiently large-amplitude and left-handed ‘‘pump waves’’ propagating parallel to the background magnetic field were shown to stabilize a moderately dense beam in a proton plasma against the ...

It has been recently shown that the presence of large amplitude left-hand polarized waves can change the linear properties of ion-beam plasma electromagnetic instabilities [Gomberoff, 2003]. Thus, it was shown that in the ...

Ion beam-plasma interactions are the source of wave activity in several space environments. Therefore the study of these waves and their parametric decays are very important in space physics. Thus we study parametric decays ...

It is well known that ion-beam-plasma interactions can destabilize right- and left-hand polarized electromagnetic waves. Owing to the fact that these instabilities have mostly been studied numerically by solving the ...

Depending on the physical conditions involved, beam plasma systems may reveal new unstable regimes triggered by wave instabilities of different natures. We show through linear theory and numerical simulations the existence ...

It has been shown that a large amplitude Alfv́n wave can stabilize linear magnetosonic instabilities triggered by an ion beam. This phenomenon occurs for large amplitude waves above a threshold value. Here the effect of a ...

We study the stability of the cold-plasma dispersion relation for circularly polarized waves in a plasma composed of an ion background and an ion beam. The presence of the beam introduces a resonant branch into the dispersion ...

This paper studies the effect of nonlinear left-hand polarized waves supported by a proton beam on the linear circularly polarized instabilities driven by the same beam. It shows that the nonlinear wave can either stabilize ...
