In this review, an overview of the recent history of stochastic differential equations (SDEs) in
application to particle transport problems in space physics and astrophysics is given. The …

We review recent observations and modeling developments on the subject of galactic
cosmic rays through the heliosphere and in the Very Local Interstellar Medium, emphasizing …

This paper summarizes the results obtained by the team “Heliosheath Processes and the
Structure of the Heliopause: Modeling Energetic Particles, Cosmic Rays, and Magnetic …

The global features of the modulation of galactic cosmic ray protons and helium nuclei in a
very quiet heliosphere are studied with a comprehensive, three-dimensional, drift model and …

The heliospheric modulation model H el M od is a two dimensional treatment dealing with
the helio-colatitude and radial distance from Sun and is employed to solve the transport …

A perspective is given of the solar modulation of galactic cosmic rays in the heliosphere
during the extraordinary quiet solar minimum period from 2006 to 2009. This is done in the …

Context. The PAMELA experiment observed galactic proton and electron spectra down to 70
MV and 400 MV, respectively, from mid-2006 to the end of 2009 during what is called an A< …

The intensity of galactic cosmic rays (GCRs) is modulated by solar activity on various
timescales. In this study, we performed comprehensive numerical modeling of the solar …

Based on the reduced diffusion mechanism for producing Forbush decreases (Fds) in the
heliosphere, we constructed a three-dimensional (3D) diffusion barrier, and by incorporating …

In this study, a novel ab initio cosmic ray (CR) modulation code that solves a set of stochastic
transport equations equivalent to the Parker transport equation, and that uses output from a …
