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…
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…
Heat-flux Instabilities of Regularized Kappa Distributed Strahl Electrons Resolved with ALPS
Dustin L. Schröder, Marian Lazar, Rodrigo A. López +1
The fluid behavior of the solar wind is affected by the heat flux carried by the suprathermal electron populations, especially the electron strahl (or beam) that propagates along t…
Revisiting the Ulysses electron data with a triple fit of velocity distributions
Klaus Scherer, Edin Husidic, Marian Lazar +1
Given their uniqueness, the Ulysses data can still provide us with valuable new clues about the properties of plasma populations in the solar wind, and, especially, about their var…
Towards a realistic evaluation of transport coefficients in non-equilibrium space plasmas
Edin Husidic, Klaus Scherer, Marian Lazar +2
Recent studies have outlined the interest for the evaluation of transport coefficients in space plasmas, where the observed velocity distributions of plasma particles are condition…
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…
On the applicability of -distributions
Klaus Scherer, Horst Fichtner, Hans-Jörg Fahr +1
The standard (non-relativistic) -distribution is widely used to fit data and to describe macroscopic thermodynamical behavior, e.g.\ the pressure (temperature) as the second mom…
Firehose instabilities triggered by the solar wind suprathermal electrons
S. M. Shaaban, M. Lazar, R. A. Lopez +2
In collision-poor plasmas from space, e.g., solar wind, terrestrial magnetospheres, kinetic instabilities are expected to play a major role in constraining the temperature anisotro…
On the entropy of plasmas described with regularized -distributions
H. Fichtner, K. Scherer, M. Lazar +2
In classical thermodynamics the entropy is an extensive quantity, i.e.\ the sum of the entropies of two subsystems in equilibrium with each other is equal to the entropy of the ful…
Regularized -distributions with non-diverging moments
K. Scherer, H. Fichtner, M. Lazar
For various plasma applications the so-called (non-relativistic) -distribution is widely used to reproduce and interpret the suprathermal particle populations exhibiting a power…
On the interpretation and applicability of -distributions
M. Lazar, H. Fichtner, P. H. Yoon
The generally accepted representation of -distributions in space plasma physics allows for two different alternatives, namely assuming either the temperature or the thermal velo…
