In this paper we assess possible roles of stochastic acceleration by random electric field and
plasma motion in the production and transport of energetic particles in the heliosphere …

There has been a remarkable discovery concerning particles that are accelerated in the
solar wind. At low energies, in the region where the particles are being accelerated, the …

In the last decade a significant discovery has been made in the heliosphere: the spectrum of
particles accelerated in both the inner heliosphere and in the heliosheath is the same: a …

Particle acceleration is one of the most important topics in plasma astrophysics as well as in
cosmic-ray astrophysics. The heliosphere is an ideal astrophysical laboratory, wherein one …

There has been a remarkable discovery in the heliosphere. Ions accelerated in disparate
plasma conditions–the quiet solar wind, disturbed conditions downstream from shocks, and …

We discuss recent observations of energetic particles and cosmic rays lending insight into
how these particles are influenced by the interplanetary magnetic field and what can be …

Three acceleration processes of charged particles in cosmic plasmas are reviewed:
resonant stochastic acceleration, diffusive shock acceleration and conversion of bulk motion …

We study the propagation of energetic particles, accelerated by interplanetary shock waves,
upstream of the shock, considering the possibility of having anomalous transport. The …

Stochastic acceleration of electrons and protons by waves propagating parallel to the large-
scale magnetic fields of magnetized plasmas is studied with emphasis on the feasibility of …

Diffusion theory has proven enormously successful in explaining a wide range of cosmic ray
phenomena, but a satisfactory explanation of how energetic charged particles are scattered …
