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…
A Case for Electron-Astrophysics
Daniel Verscharen, Robert T. Wicks, Olga Alexandrova +27
A grand-challenge problem at the forefront of physics is to understand how energy is transported and transformed in plasmas. This fundamental research priority encapsulates the con…
Spreading protons in the heliosphere: a note on cross-field diffusion effects
Nicolas Wijsen, Angels Aran, Jens Pomoell +1
We study how a high-speed solar wind stream embedded in a slow solar wind affects the transport and energy changes of solar energetic protons in interplanetary space, assuming diff…
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,…
Interplanetary spread of solar energetic protons near a high-speed solar wind stream
Nicolas Wijsen, Angels Aran, Jens Pomoell +1
We study how a high-speed solar wind stream embedded in a slow solar wind influences the spread of solar energetic protons in interplanetary space. To model the energetic protons,…
The Interplay of the Solar Wind Core and Suprathermal Electrons: A Quasilinear Approach for Firehose Instability
S. M. Shaaban, M. Lazar, P. H. Yoon +1
In the solar wind an equipartition of kinetic energy densities can be easily established between thermal and suprathermal electrons and the instability conditions are markedly alte…
