Extended scenarios for solar radio emissions with downshifted electron beam plasma excitations
M. Lazar, R. A. López, S. M. Shaaban +2
First-principle studies of radiative processes aimed at explaining the origin of type II and type III solar radio bursts raise questions on the implications of downshifted electron…
Numerical simulations of temperature anisotropy instabilities stimulated by suprathermal protons
S. M. Shaaban, R. A. Lopez, M. Lazar +1
The new in situ measurements of the Solar Orbiter mission contribute to the knowledge of the suprathermal populations in the solar wind, especially of ions and protons whose charac…
Decoding the formation of hammerhead ion populations observed by Parker Solar Probe
Shaaban M. Shaaban, M. Lazar, R. A. López +2
In situ observations by the Parker Solar Probe (PSP) have revealed new properties of the proton velocity distributions, including hammerhead features that suggest non-isotropic bro…
Mixing the solar wind proton and electron scales. Theory and 2D-PIC simulations of firehose instability
R. A. López, A. Micera, M. Lazar +5
Firehose-like instabilities (FIs) are cited in multiple astrophysical applications. Of particular interest are the kinetic manifestations in weakly-collisional or even collisionles…
Quasilinear Approach of the Whistler Heat-Flux Instability in the Solar Wind
S. M. Shaaban, M. Lazar, P. H. Yoon +2
The hot beaming (or strahl) electrons responsible for the main electron heat-flux in the solar wind are believed to be self-regulated by the electromagnetic beaming instabilities,…
Instability constraints for the electron temperature anisotropy in the slow solar wind. Thermal core vs. suprathermal halo
M. Lazar, S. M. Shaaban, V. Pierrard +2
This letter presents the results of an advanced parametrization of the solar wind electron temperature anisotropy and the instabilities resulting from the interplay of the (bi-)Max…
Shaping the solar wind temperature anisotropy by the interplay of electron and proton instabilities
S. M. Shaaban, M. Lazar, S. Poedts +1
A variety of nonthermal characteristics like kinetic, e.g., temperature, anisotropies and suprathermal populations (enhancing the high energy tails of the velocity distributions) a…
Firehose constraints for the solar wind suprathermal electrons
M. Lazar, S. M. Shaaban, S. Poedts +1
The indefinite increase of temperature predicted by the solar wind expansion in the direction parallel to the interplanetary magnetic field is already notorious for not being confi…
