Modeling drift along the heliospheric wavy neutral sheet
(IOP Publishing, 2012)
Drift along the wavy heliospheric neutral sheet is believed to play an important role in cosmic-ray modulation and can explain the peaked versus flat intensity profiles during consecutive solar magnetic epochs. Modulation ...
Modelling of galactic carbon in an asymmetrical heliosphere: effects of asymmetrical modulation conditions
(Elsevier, 2012)
Observations of galactic cosmic rays (GCRs) from the two Voyager spacecraft inside the heliosheath indicate significant differences between them, suggesting that in addition to a possible global asymmetry in the north–south ...
Three-dimensional wavy heliospheric current sheet drifts
(IOP publishing, 2012)
We present an analytic method to determine the directions of the three-dimensional (3D) heliospheric current sheet (HCS) drift for any tilt angle based on Parker's heliospheric magnetic field and compare it with published ...
A generalized diffusion tensor for fully anisotropic diffusion of energetic particles in the heliospheric magnetic field
(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 ...
Modelling heliospheric current sheet drift in stochastic cosmic ray transport models
(Springer, 2012)
Drifts are one of the major cosmic ray modulation mechanisms in the heliosphere. Three types of drifts occur in the background heliospheric magnetic field, namely curvature, gradient and current sheet drifts. The last ...
Modeling ground and space based cosmic ray observations
(Elsevier, 2012)
After entering our local astrosphere (called the heliosphere), galactic cosmic rays, as charged particles, are affected by the Sun’s turbulent magnetic field. This causes their intensities to decrease towards the inner ...
