Turbulence in the outer heliosphere
Federico Fraternale, Laxman Adhikari, Horst Fichtner +9
The solar wind (SW) and local interstellar medium (LISM) are turbulent media. Their interaction is governed by complex physical processes and creates heliospheric regions with sign…
On the Generation of Compressible Mirror-mode Fluctuations in the Inner Heliosheath
Horst Fichtner, Jens Kleimann, Peter H. Yoon +3
Measurements made with the Voyager 1 spacecraft indicate that significant levels of compressive fluctuations exist in the inner heliosheath. Some studies have already been performe…
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…
Uncertainties in the heliosheath ion temperatures
Klaus Scherer, Hans Jörg Fahr, Horst Fichtner +3
The Voyager plasma observations show that the physics of the heliosheath is rather complex, and especially that the temperature derived from observation differs from expectations.…
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…
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,…
