Particle Acceleration in Solar Flares and Escape Into Interplanetary Space

2006
We review the physics of particle acceleration and kinematics in solar flares under the particular aspect of their escape and propagation into interplanetary space. The topics include the magnetic topology in acceleration regions, the altitude of flare acceleration regions, evidence for bi-directional acceleration, the asymmetry of upward versus ...

Adiabatic Fermi acceleration of energetic particles between converging interplanetary shock waves

Journal of Geophysical Research, 1976
The process of adiabatic acceleration of relativistic cosmic rays between two converging shocks, through the first-order Fermi mechanism, to which the unusual ground level event (GLE) of August 4, 1972, was attributed earlier is examined quantitatively, the nature of interplanetary shock waves and their propagation being taken into account.

The acceleration of energetic charged particles by interplanetary and supernova shock waves

AIP Conference Proceedings, 1979
Pioneer 11 observations of energetic proton acceleration in interplanetary shock are in good agreement with predictions of the V↘×B↘ electric field model of shock acceleration. The V↘×B↘ model predicts that relativistic particles are accelerated by a factor of 2–15 in kinetic energy during a single encounter with a quasi‐perpendicular (ψ≳75 ...

Particle Acceleration and Alfv’en Wave Generation at the April 4, 2001 Interplanetary Shock

Journal of Experimental and Theoretical Physics, 2018
Based on the theory of diffusive shock acceleration of charged particles, we investigate the formation of proton spectra and the generation of an Alfv’en turbulence spectrum by accelerated (storm) particles at the interplanetary shock front in the event occurred at 14:22 UT on April 4, 2001.

Relationship of solar flare accelerated particles to solar energetic particles (SEPs) observed in the interplanetary medium

Advances in Space Research, 2005
Abstract Observations of hard X-ray (HXR)/γ-ray continuum and γ-ray lines produced by energetic electrons and ions, respectively, colliding with the solar atmosphere, have shown that large solar flares can accelerate ions up to many GeV and electrons up to hundreds of MeV.

Comparison of Particle Acceleration at Planetary Bow Shocks and Interplanetary Shocks

The spatial size of collisionless shock waves is suggested to play an important role in determining the maximum energy gain of particles accelerated at heliospheric and astrophysical shocks. In addition, shocks energize particles with different starting/upstream energies differently.
