On the interplay of solar wind proton and electron instabilities: Linear and quasi-linear approaches
S. M. Shaaban, M. Lazar, R. A. López +1
Important efforts are currently made for understanding the so-called kinetic instabilities, driven by the anisotropy of different species of plasma particles present in the solar w…
Electromagnetic ion cyclotron instability stimulated by the suprathermal ions in space plasmas: A quasi-linear approach
S. M. Shaaban, M. Lazar, R. Schlickeiser
In collision-poor space plasmas protons with an excess of kinetic energy or temperature in direction perpendicular to background magnetic field can excite the electromagnetic ion c…
Electromagnetic Ion-Ion Instabilities in Space Plasmas: Effects of Suprathermal Populations
S. M. Shaaban, M. Lazar, R. A. López +1
In collision-poor plasmas from space, three distinct ion-ion instabilities can be driven by the proton beams streaming along the background magnetic field: left-hand resonant, non-…
Alternative high plasma beta regimes of electron heat-flux instabilities in the solar wind
R. A. López, M. Lazar, S. M. Shaaban +2
The heat transport in the solar wind is dominated by the suprathermal electron populations, i.e., a tenuous halo and a field-aligned beam/strahl, with high energies and antisunward…
A firehose-like aperiodic instability of the counter-beaming electron plasmas
R. A. López, M. Lazar, S. M. Shaaban +2
Depending on the physical conditions involved the beam plasma systems may reveal new unstable regimes triggered by the wave instabilities of different nature. We show through linea…
Whistler instabilities from the interplay of electron anisotropies in space plasmas: A quasilinear approach
S. M. Shaaban, M. Lazar
Recent statistical studies of observational data unveil relevant correlations between whistler fluctuations and the anisotropic electron populations present in space plasmas, e.g.,…
Whistler instability stimulated by the suprathermal electrons present in space plasmas
M. Lazar, R. A. Lopez, S. M. Shaaban +2
In the absence of efficient collisions, deviations from thermal equilibrium of plasma particle distributions are controlled by the self-generated instabilities. The whistler instab…
Quasilinear approach of the cumulative whistler instability in fast solar winds: Constraints of electron temperature anisotropy
S. M. Shaaban, M. Lazar, P. H. Yoon +1
Context. Solar outflows are a considerable source of free energy which accumulates in multiple forms like beaming (or drifting) components and/or temperature anisotropies. However,…
Firehose instabilities triggered by the solar wind suprathermal electrons
S. M. Shaaban, M. Lazar, R. A. Lopez +2
In collision-poor plasmas from space, e.g., solar wind, terrestrial magnetospheres, kinetic instabilities are expected to play a major role in constraining the temperature anisotro…
Clarifying the solar wind heat-flux instabilities
S. M. Shaaban, M. Lazar, S. Poedts
In the solar wind electron velocity distributions reveal two counter-moving populations which may induce electromagnetic (EM) beaming instabilities known as heat flux instabilities…
Dual Maxwellian-Kappa modelling of the solar wind electrons: new clues on the temperature of Kappa populations
M. Lazar, V. Pierrard, S. M. Shaaban +2
Context. Recent studies on Kappa distribution functions invoked in space plasma applications have emphasized two alternative approaches which may assume the temperature parameter e…
