Ion firehose and ion cyclotron instability with subtracted-Kappa distributions
Luiz F. Ziebell, Rudi Gaelzer, Danny Summers
In the present paper we discuss numerical solutions of the dispersion relation for electromagnetic waves propagating along the lines of an ambient magnetic field, considering param…
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…
Electrostatic waves in astrophysical Druyvesteyn plasmas: I. Langmuir waves
Simon Tischmann, Rudi Gaelzer, Dustin Schröder +2
Plasmas in various astrophysical systems are in non-equilibrium states as evidenced by direct in-situ measurements in the solar wind, solar corona and planetary environments as wel…
Influence of plasma particle flow on dust grain charging and on particle number density
L. B. De Toni, L. F. Ziebell, R. Gaelzer
This study explores the dynamic evolution of dust electrical potential and plasma particle number densities with a focus on the charging of dust grains through electron and ion abs…
Collisional charging of dust particles by suprathermal plasmas. II -- Regularized Kappa distributions
Rudi Gaelzer, Luiz Fernando Ziebell
We study the effects of the velocity distribution functions of the plasma particles on the equilibrium charge of dust grains, acquired through inelastic collisions of the particles…
Single-Mode Wave Decay
Guilherme T. Irumé, Joel Pavan, Rudi Gaelzer
The usual approach on electrostatic wave decay process for a weak beam-plasma system considers two different wave modes interplaying, the Langmuir and ion-sound mode. In the presen…
