(Blackwell Publishing Ltd, 1998)We study the stability of electromagnetic waves for nongyrotropic velocity distribution functions in a solar-wind-like plasma. The dispersion relation is solved numerically in closed form. On the basis of recently reported ...
-
(Blackwell Publishing Ltd, 2008)Alfvén/ion-cyclotron waves have been observed in several regions of the magnetosphere. Parametric decays of finite amplitude Alfvén/ion- cyclotron waves in the presence of He+ ions and a mixed population of thermal and hot ...
-
(Blackwell Publishing Ltd, 2000)It is well known that in plasmas with β = (νs/νA)2 < 1 (νs is the ion acoustic velocity and νA is the Alfvén velocity), Alfvén waves propagating along an external magnetic field can have three kinds of parametric ...
-
(Blackwell Publishing Ltd, 2001)We study ion acoustic damping effects on parametric decays of right-hand-polarized electromagnetic waves. We do this because ion beams have been observed in a variety of space environments, and consequently, these waves ...
-
(Blackwell Publishing Ltd, 2005)[1] It is shown that ion-acoustic waves propagating along an external magnetic field and generated by parametric decays of circularly polarized finite amplitude waves have the properties of ion-acoustic waves observed ...
-
(Blackwell Publishing Ltd, 2009)It is well known that nonlinear electrostatic instabilities can be triggered in a plasma with streaming ion species in the presence of finite-amplitude Alfvén cyclotron waves. The instability occurs when the phase velocity ...
-
(Blackwell Publishing Ltd, 2007)The effects of a finite-amplitude Alfvén wave in a plasma system with a proton and an alpha-particle beam, are studied. The system is described by a fourteenth-order polynomial providing, thereby, many decay channels for ...
