The role of radial perpendicular diffusion and latitude dependent acceleration along the solar
(Elsevier, 2008)
A numerical model, based on Parker’s transport equation, describing the modulation of anomalous cosmic rays and containing diffusive shock acceleration is applied. The role of radial perpendicular diffusion at the solar ...
Cosmic rays in the dynamic heliosphere
(Japan Society of Plasma Science and Nuclear Fusion Research, 2009)
he relation between the dynamics of the heliosphere,
its shape and geometry, so
lar activity and cosmic ray
variations is addressed. The global features of the helio
sphere influence what happens
inside its boundaries ...
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 ...
Cosmic ray modulation in the outer heliosphere: predictions for cosmic ray intensities up to the heliopause along Voyager 1 and 2 trajectories
(Elsevier, 2011)
Time dependent cosmic ray modulation in the outer heliosphere is calculated and results are compared to Voyager 1 and 2 observations using a two-dimensional time-dependent cosmic ray transport model. We predict possible ...
Challenges to cosmic ray modeling: from beyond the solar wind termination shock
(Elsevier, 2008)
Voyager 1 crossed the solar wind termination shock on December 16, 2004 at a distance of 94 AU from the Sun, to become the first spacecraft to explore the termination shock region and to enter the heliosheath, the final ...
