Comparison of different analytic heliospheric magnetic field configurations and their significance for the particle injection at the termination shock
Scherer, K.; Burger, R.A.; Fichtner, H.; Effenberger, F.; Wiengarten, T. (EDP Sciences, 2010) -
Cosmic ray modulation beyond the heliopause: a hybrid modeling approach
Strauss, R.D.; Potgieter, M.S.; Ferreira, S.E.S.; Fichtner, H.; Scherer, K. (IOP Publishing, 2013)Results from a newly developed hybrid cosmic ray (CR) modulation model are presented. In this approach, the transport of CRs is computed by incorporating the plasma flow from a magnetohydrodynamic model for the heliospheric ... -
A generalized diffusion tensor for fully anisotropic diffusion of energetic particles in the heliospheric magnetic field
Effenberger, F.; Strauss, R.D.; Fichtner, H.; Scherer, K.; Barra, S.; Kleimann, J. (IOP Publishing, 2012)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, field-aligned frame. We reexamine the ... -
Ionization rates in the heliosheath and in astrosheaths: spatial dependence and dynamical relevance
Scherer, K.; Ferreira, S.E.S.; Fichtner, H.; Fahr, H.-J.; Bzowski, M. (EDP Sciences, 2014)Context. In the heliosphere, especially in the inner heliosheath, mass-, momentum-, and energy-loading induced by the ionization of neutral interstellar species plays an important, but for some species, especially helium, ... -
On cosmic ray modulation beyond the heliopause: where is the modulation boundary?
Scherer, K.; Strauss, R.D.; Ferreira, S.E.S.; Potgieter, M.S.; Fichtner, H. (IOP Publishing, 2011)Two of the paradigms in modeling the transport of galactic cosmic rays are that the modulation boundary is the heliopause and that the local interstellar spectra are identical to the galactic cosmic ray spectra. Here we ...
