Electron Holes in a Regularized Kappa Background

Fernando Haas, Horst Fichtner, Klaus Scherer

The pseudopotential method is used to derive electron hole structures in a suprathermal plasma having a regularized probability distribution function background. The regularize…

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…

A new low-beta regime for unstable proton firehose modes in bi-Kappa distributed plasmas

S. M. Shaaban, M. Lazar, R. F. Wimmer-Schweingruber +1

In the solar wind plasma an excess of kinetic temperature along the background magnetic field stimulates proton firehose modes to grow if the parallel plasma beta parameter is suff…

Linear Dispersion Theory of Parallel Electromagnetic Modes for Regularized Kappa-Distributions

Edin Husidic, Marian Lazar, Horst Fichtner +2

The velocity particle distributions measured in-situ in space plasmas deviate from Maxwellian (thermal) equilibrium, showing enhanced suprathermal tails which are well described by…

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…
