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…
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…
Heliosheath Processes and the Structure of the Heliopause: Modeling Energetic Particles, Cosmic Rays, and Magnetic Fields
N. V. Pogorelov, H. Fichtner, A. Czechowski +11
This paper summarizes the results obtained by the team "Heliosheath Processes and the Structure of the Heliopause: Modeling Energetic Particles, Cosmic Rays, and Magnetic Fields" s…
A generalized two-component model of solar wind turbulence and ab initio diffusion mean free paths and drift lengthscales of cosmic rays
Tobias Wiengarten, Sean Oughton, Eugene Engelbrecht +3
We extend a two-component model for the evolution of fluctuations in the solar wind plasma so that it is fully three-dimensional (3D) and also coupled self-consistently to the larg…
Comic ray flux anisotropies caused by astrospheres
K. Scherer, R. D. Strauss, S. E. S. Ferreira +1
Huge astrospheres or stellar wind bubbles influence the propagation of cosmic rays at energies up to the TeV range and can act as small-scale sinks decreasing the cosmic ray flux.…
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…
Simultaneous Analysis of Recurrent Jovian Electron Increases and Galactic Cosmic Ray Decreases
P. Kühl, N. Dresing, P. Dunzlaff +10
The transport environment for particles in the heliosphere, e.g. galactic cosmic rays (GCRs) and MeV electrons (including those originating from Jupiters magnetosphere), is defined…
MHD Simulation of the Inner-Heliospheric Magnetic Field
T. Wiengarten, J. Kleimann, H. Fichtner +4
Maps of the radial magnetic field at a heliocentric distance of ten solar radii are used as boundary conditions in the MHD code CRONOS to simulate a 3D inner-heliospheric solar win…
A Generalized Diffusion Tensor for Fully Anisotropic Diffusion of Energetic Particles in the Heliospheric Magnetic Field
Frederic Effenberger, Horst Fichtner, Klaus Scherer +3
The spatial diffusion of cosmic rays in turbulent magnetic fields can, in the most general case, be fully anisotropic, i.e. one has to distinguish three diffusion axes in a local,…
