Anisotropic diffusion of galactic cosmic ray protons and their steady-state azimuthal distribution
Frederic Effenberger, Horst Fichtner, Klaus Scherer +1
Galactic transport models for cosmic rays involve the diffusive motion of these particles in the interstellar medium. Due to the large-scale structured galactic magnetic field this…
A novel code for numerical 3-D MHD studies of CME expansion
Jens Kleimann, Andreas Kopp, Horst Fichtner +1
A recent third-order, essentially non-oscillatory central scheme to advance the equations of single-fluid magnetohydrodynamics (MHD) in time has been implemented into a new numeric…
On the low-frequency boundary of Sun-generated MHD turbulence in the slow solar wind
Bidzina M. Shergelashvili, Horst Fichtner
New aspects of the slow solar wind turbulent heating and acceleration are investigated. A physical meaning of the lower boundary of the Alfvén wave turbulent spectra in the solar a…
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,…
