Wave instabilities in anisotropic regularized Kappa plasmas: New plasma dispersion functions and numerical validation
Rudi Gaelzer, Dustin L. Schröder, Marian Lazar +1
Plasmas in space and astrophysical environments are frequently found in (quasi-)stationary states not in thermal equilibrium, indicated by velocity distribution functions (VDFs) fe…
Hybrid simulations of the proton beam instabilities in the young solar wind. The formation of hammerhead-like distributions
R. A. López, Shaaban M. Shaaban, M. Lazar +4
Parker Solar Probe (PSP) observations in the young solar wind reveal new properties of both plasma particle velocity distributions (VDs) and associated electromagnetic (EM) wave fl…
Kinetic-based macro-modeling of the solar wind at large heliocentric distances: Kappa electrons at the exobase
Alexander Vinogradov, Marian Lazar, Ioannis Zouganelis +2
Recent evidence from Parker Solar Probe on the suprathermal electrons with Kappa-type velocity distributions in the outer corona has revived interest in the kinetic-based macro-mod…
Quasi-linear approach of bi-Kappa distributed electrons with dynamic parameter. EMEC instability
Pablo S Moya, Roberto E Navarro, Marian Lazar +3
In recent years, significant progress has been made in the velocity-moment-based quasi-linear (QL) theory of waves and instabilities in plasmas with nonequilibrium velocity distrib…
