On the modeling of oblique firehose instabilities in regularized Kappa plasmas using ALPS
D. L. Schröder, M. Lazar, H. Fichtner +2
In-situ measurements in space plasmas indicate that the velocity distributions of charged particles are not in thermal equilibrium, deviating from a standard Maxwellian mainly due…
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…
A dispersion function for the regularized kappa distribution function
Rudi Gaelzer, Horst Fichtner, Klaus Scherer
In this work we define the plasma dispersion function for a suprathermal plasma described with a regularized kappa distribution. As is known from Maxwellian as well as (standard) k…
Instability constraints for the electron temperature anisotropy in the slow solar wind. Thermal core vs. suprathermal halo
M. Lazar, S. M. Shaaban, V. Pierrard +2
This letter presents the results of an advanced parametrization of the solar wind electron temperature anisotropy and the instabilities resulting from the interplay of the (bi-)Max…
Dual Maxwellian-Kappa modelling of the solar wind electrons: new clues on the temperature of Kappa populations
M. Lazar, V. Pierrard, S. M. Shaaban +2
Context. Recent studies on Kappa distribution functions invoked in space plasma applications have emphasized two alternative approaches which may assume the temperature parameter e…
The return of the bow shock
Klaus Scherer, Horst Fichtner
Recently it has been discussed whether a bow shock ahead of the heliospheric stagnation region does exist or not. This discussion was triggered by measurements indicating that the…
