Fe/O Ratios in Interplanetary Shock Accelerated Particles
Space Science Reviews, 2007It is widely accepted that diffusive shock acceleration is an important process in the heliosphere, in particular in producing the energetic particles associated with interplanetary shocks driven by coronal mass ejections. In its simplest formulation shock acceleration is expected to accelerate ions with higher mass to charge ratios less efficiently ...

Interplanetary particle acceleration, modulation and drift
Reviews of Geophysics, 1979This report is concerned mainly with the contribution of U. S. scientists, during the period 1975–1978, to the general area of particle acceleration and transport in the solar wind, excluding particles of solar origin. Other work is cited only when it bears directly on the subject being discussed.

Particle acceleration and Alfvén wave generation by an interplanetary shock
Astronomy Letters, 2016Based on the event observed by ISEE 3 near the Earth’s orbit at 01:21 UT on April 5, 1979, we investigate the diffusive shock acceleration of ions and the generation of Alfven waves by accelerated particles near the quasi-parallel parts of interplanetary shock fronts within a quasi-linear approach.

Particle acceleration by coronal and interplanetary shock waves
Advances in Space Research, 1982Utilizing many years of observation from deep space and near-earth spacecraft a theoretical understanding has evolved on how ions and electrons are accelerated in interplanetary shock waves. This understanding is now being applied to solar flare-induced shock waves propagating through the solar atmosphere.

Charged particle acceleration processes in the interplanetary medium
Advances in Space Research, 1989Abstract Selected aspects of energetic (>35 keV) ion acceleration processes in three regions of the heliosphere are reviewed: at interplanetary travelling shocks near 1 AU, in the outer heliosphere and in cometary environments. Clear examples of diffusive acceleration events at quasi-parallel shocks as well as of shock drift acceleration events at ...

Particle Acceleration Processes in Interplanetary Space
1985The preceeding chapters have been concerned mainly with multiple scattering, diffusion, and convective transport of particles. In passing, some processes of particle energy variations have been considered, such as adiabatic deceleration in expanding streams of magnetic inhomogeneities (§8,1, 12, 13) and in large-scale magnetic fields frozen into the ...

Acceleration of low‐energy protons and alpha particles at interplanetary shock waves
Journal of Geophysical Research: Space Physics, 1983We have investigated low‐energy protons and alpha particles in the energy range 30 keV/charge to 150 keV/charge associated with three different interplanetary shock waves in the immediate preshock and postshock region. The data were obtained with the Max‐Planck‐Institut/University of Maryland sensor system on ISEE 3.

Energy spectrum of low-energy fluxes of particles accelerated by interplanetary shocks
Advances in Space Research, 1995Abstract The injection rate of particles at the front of interplanetary shocks has usually been studied locally, around the shock passage by the observer's position, but little is known of how the efficiency of the particle-acceleration process evolves as the shock propagates from the Sun to the Earth.

Origin of coronal and interplanetary shock and particle acceleration of a flare/CME event
Advances in Space Research, 2003By using radio data from ground-based telescopes (from 270 MHz to 25 MHz), and from the Radio and Plasma Wave experiment (WAVES) on board the WIND spacecraft (1–14 MHz and several kHz-11 MHz), as well as FY -2 satellite data, the origin of coronal and interplanetary shock and particle acceleration of the 14 July 2000 flare/CME event (the Bastille day ...

Particle Acceleration in Solar Flares and Escape Into Interplanetary Space
2006We 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 ...
