Modelling the effects of scattering parameters on particle-drift in the solar modulation of galactic cosmic rays
(Elsevier, 2015)
It is well known that particle drift motions are suppressed by diffusive scattering as established by direct numerical simulations. The effect of constant scattering on the drift velocities of charged particles has always ...
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 ...
A calibration neutron monitor: statistical accuracy and environmental sensitivity
(Elsevier, 2010)
This paper is a follow-on of that of Krüger et al. [Krüger, H., Moraal, H., Bieber, J.W., Clem, J.M., Evenson, P.A., Pyle, K.R., Duldig, M.L., Humble, J.E. A calibration neutron monitor: energy response and instrumental ...
The dynamic heliosphere, solar activity, and cosmic rays
(Elsevier, 2010)
This brief review addresses the relation between solar activity, cosmic ray variations and the dynamics of the heliosphere. The global features of the heliosphere influence what happens inside its boundaries on a variety ...
Cosmic ray modulation with a Fisk-type heliospheric magnetic field and a latitude-dependent solar wind speed
(Elsevier, 2009)
The effect of a latitude-dependent solar wind speed on a Fisk heliospheric magnetic field [Fisk, L. A. Motion of the footpoints of heliospheric magnetic field lines at the Sun: implications for recurrent energetic particle ...
Modelling and observing Jovian electron propagation times in the inner heliosphere
(Elsevier, 2013)
The propagation of Jovian electrons in interplanetary space was modelled by solving the relevant transport equation numerically through the use of stochastic differential equations. This approach allows us to calculate, ...
New insights from modeling the neutral heliospheric current sheet
(Springer, 2015)
Recently, the modulation of cosmic rays in the heliosphere
has increasingly been studied by solving the well
known transport equation via an approach based on stochastic
differential equations. This approach, which is ...
Modulation of galactic cosmic rays in a north-south asymmetrical heliosphere
(Elsevier, 2011)
Observations made with the two Voyager spacecraft confirmed that the solar wind decelerates to form the heliospheric termination shock. Voyager 1 crossed this termination shock at ∼94 AU in 2004, while Voyager 2 crossed ...
Modelling of low-energy galactic electrons in the heliosheath
(Elsevier, 2011)
The modulation of cosmic ray electrons in the heliosphere plays an important role in improving our understanding and assessment of the processes applicable to low-energy galactic electrons. A full three-dimensional numerical ...
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 ...
