Time-dependent Acceleration of Solar Wind Particles at Interplanetary Traveling Shocks
AIP Conference Proceedings, 2008A time‐dependent focused transport model is used to model how solar wind protons are injected from the suprathermal tail of the solar wind distribution into diffusive shock acceleration at both a strong and a weak coronal mass ejection‐driven shock. It is discussed how the temporal evolution of the injection and acceleration process can result in solar

Particle acceleration and MHD wave excitation upstream of interplanetary shocks
Advances in Space Research, 1984The theory of diffusive shock acceleration and its application in interplanetary space are reviewed. Special emphasis is placed on the distinction between diffusive and shock-drift shock acceleration, on ion-excitation of MHD waves upstream of the shock and the resulting self-consistent configuration of waves and accelerated ions, and on the ...

We report the results of a study of the 12-hour average distribution functions of high Z nuclei as measured over a 10-day interval on the Ulysses spacecraft at a helioradius of ∼5.2 A.U. We use the good time and atomic mass resolution of the composition aperture of the HI-SCALE instrument to determine the form of the distribution functions for C, O, Ne,

Particle Acceleration and Alfv’en Wave Generation at the April 4, 2001 Interplanetary Shock
Journal of Experimental and Theoretical Physics, 2018Based 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.

The acceleration of energetic charged particles by interplanetary and supernova shock waves
AIP Conference Proceedings, 1979Pioneer 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 ...

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.Martin Lindberg +3 more
