TL;DR: In this article, the authors provide an overview of current efforts in the theory and modeling of CMEs, focusing on how energy stored in the coronal magnetic field can be released violently to drive CME driven shocks.

TL;DR: In this article, the authors measured the proton spectra of the Sun from 2006 July to 2009 December by PAMELA and compared the data with a state-of-the-art three-dimensional model of solar modulation.
Journal ArticleDOI
Modeling the modulation of galactic and jovian electrons by stochastic processes
TL;DR: In this article, a numerical modulation model was proposed to study the transport of galactic and Jovian electrons in the heliosphere, which employs stochastic differential equations (SDEs) to solve the corresponding transport equation in five dimensions (time, energy, and three spatial dimensions) which is difficult to accomplish with the numerical schemes used in finite difference models.
Journal ArticleDOI
Modulation of Jovian and galactic electrons in the heliosphere: 1. Latitudinal transport of a few MeV electrons
TL;DR: In this article, the radial transport of ∼16 MeV electrons is studied by comparing the model results with the −16 MEV electron intensities observed by Pioneer 10 up to ∼70 AU, and the relative contributions of the Jovian and galactic electrons to the total electron intensity are shown along the Pioneer 10 trajectory.
Journal ArticleDOI
The simulation of complete 11 and 12 year modulation cycles for cosmic rays in the heliosphere using a drift model with global merged interaction regions
J. A. le Roux,M. S. Potgieter +1 more
TL;DR: Potegieter et al. as mentioned in this paper studied the effects of two consecutive, identical global MIRs, together with a changing wavy HNS, on long-term modulation.
