Galactic cosmic rays in the heliosphere
Advances in Space Research, 2004Abstract Galactic cosmic rays entering the heliosphere are subjected to four modulation processes: diffusion, convection, adiabatic deceleration in the expanding solar wind, gradient, curvature and current sheet drifts. These particles also encounter the termination shock where they may get re-accelerated via diffusive shock acceleration to reach ...

Galactic Cosmic Rays and the Light Elements
Space Science Reviews, 2001The study of the light elements abundances in low metallicity stars offers a unique way to learn about the past content of our Galaxy in energetic particles (EPs). This study teaches us that either the light elements are not produced by cosmic rays interactions in the interstellar medium (ISM), as has been thought for 30 years, or the cosmic rays are ...

In the early years of the twentieth century, many scientists were baffled by observations of a slow leakage of electric charge from well insulated bodies. With the discovery of the radioactivity of uranium and radium, it was found that while a part of the loss of charge could be due to ionization by radiation from these substances, it was clear that a ...

We have shown in Chap. 16 that the acceleration of galactic cosmic rays below a few 1015 eV/nucl. with power law momentum spectra can be well explained by diffusive shock wave acceleration near galactic supernova remnants, which also, by the overall power requirements (see Chap. 7), are the most probable sources of galactic cosmic rays. Here we address

Propagation of galactic cosmic rays
Astroparticle Physics, 2012Abstract The theoretical aspects of cosmic ray transport in the Galaxy are discussed. The emphasis is on the diffusion model of cosmic ray propagation. The results of the empirical modelling are combined with the approach based on the kinetic theory of particle interaction with random magnetic fields.

Galactic Propagation of Cosmic Rays
1983After introducing various phenomenological models of cosmic ray propagation in the galaxy, we examine how some of thera fare when compared to the data. We show that a model based on resonant diffusion of cosmic rays off an interstellar spectrum of hydromagnetic waves can account for the presently available evidence on cosmic rays and the interstellar ...
