Modeling complex plasma instabilities in space plasmas - Three-component electron formalism of heat-flux instabilities
Dustin L. Schröder, Marian Lazar, Horst Fichtner +2
Despite the fact that electrons observed in situ in space plasmas have three major components-the quasi-thermal core, suprathermal halo, and strahl-the analysis of instabilities tr…
Wave-particle equilibria with heavy ions in weakly collisional space plasmas
Nicolás Villarroel-Sepúlveda, Daniel Verscharen, Pablo S. Moya +2
Space plasmas are weakly collisional since characteristic time scales related to Coulomb collisions are much larger than those of Larmor gyration or wave--particle interactions. Th…
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…
The role of the thermal properties of electrons on the dispersion properties of Alfvén waves in space plasmas
Nicolás Villarroel-Sepúlveda, Pablo S. Moya, Rodrigo A. López +1
Context. The transition from left-hand to right-hand polarized Alfvén waves depends on the wavenumber, the ratio of kinetic to magnetic pressure , temperature anisotropy, and…
