Particle Acceleration at Interplanetary Shocks [PDF]
Space Science Reviews, 2007 This paper briefly reviews proton acceleration at interplanetary shocks. This is key to describing the acceleration of heavy ions at interplanetary shocks because wave excitation—and hence particle scattering—at oblique shocks is controlled by the protons and not the heavy ions.

Particle Acceleration at Interplanetary Shocks [PDF]
AIP Conference Proceedings, 2008 The acceleration of interstellar pick-up ions as well as solar wind species has been observed at a multitude of interplanetary (IP) shocks by different spacecraft. This paper expands upon previous work modeling the phase space distributions of accelerated ions associated with the shock event encountered on day 292 of 1991 by the Ulysses mission at 4.5 ...

Numerical Simulations of Particle Acceleration at Interplanetary Quasi-perpendicular Shocks [PDF]
Astrophysical Journal, 2017 Abstract Using test particle simulations we study particle acceleration at highly perpendicular ( ) shocks under conditions of modeling magnetic turbulence. We adopt a backward-in-time method to solve the Newton–Lorentz equation using the observed shock parameters for quasi ...

Astronomy & AstrophysicsContext. Energetic particles are ubiquitous in space and astrophysical plasmas, and interplanetary shocks are widely regarded as one of the main particle accelerators in the heliosphere. Indeed, in situ measurements typically show that energetic particle

Efficiency of particle acceleration at interplanetary shocks: Statistical study of STEREO observations [PDF]
Astronomy and Astrophysics, 2016 Context. Among others, shocks are known to be accelerators of energetic charged particles. However, many questions regarding the acceleration efficiency and the required conditions are not fully understood. In particular, the acceleration of electrons by shocks is often questioned. Aims.

Astronomy and AstrophysicsAims. The study investigates the relevance of the seed particle population in the results of particle acceleration in interplanetary shock waves, when wave–particle interactions are treated self-consistently. Methods. We employed the SOLar Particle Acceleration in Coronal Shocks (SOLPACS) model, which is a proton acceleration simulation in shocks with ...

Energetic particle investigation using the ERNE instrument [PDF]
Annales Geophysicae, 1996 During solar flares and coronal mass ejections, nuclei and electrons accelerated to high energies are injected into interplanetary space. These accelerated particles can be detected at the SOHO satellite by the ERNE instrument.

Betatron Acceleration of Suprathermal Electrons within a Small-scale Flux Rope in the Solar Wind
The Astrophysical Journal Letters, 2023 A growing body of evidence from observations, theories, and simulations indicates that particles can be effectively accelerated in solar wind regions filled with dynamic small-scale flux ropes (FRs).

Acceleration of Solar Energetic Particles by the Shock of Interplanetary Coronal Mass Ejection [PDF]
The Astrophysical Journal, 2021 Abstract Interplanetary coronal mass ejection (ICME) shocks are known to accelerate particles and contribute significantly to solar energetic particle events. We have performed magnetohydrodynamic-particle in cell simulations of ICME shocks to understand the acceleration mechanism. These shocks vary in Alfvénic Mach numbers as well as in
