The Diffusion and Scattering of Accelerating Particles in Compressible MHD Turbulence
The Astrophysical JournalWe numerically study the diffusion and scattering of cosmic rays (CRs) together with their acceleration processes in the framework of the modern understanding of magnetohydrodynamic (MHD) turbulence. Based on the properties of compressible MHD turbulence

Compression Acceleration of Protons and Heavier Ions at the Heliospheric Current Sheet
The Astrophysical JournalRecent observations by the Parker Solar Probe (PSP) suggest that protons and heavier ions are accelerated to high energies by magnetic reconnection at the heliospheric current sheet (HCS).

Electron Acceleration at Shock Ripples: Role of Pitch-angle Diffusion
The Astrophysical JournalSuprathermal electrons are routinely observed in interplanetary space. At higher energies, there are in-situ evidences that shocks, both interplanetary shocks, often driven by fast coronal mass ejections, and terrestrial bow shocks, can accelerate ...

Electromagnetic and corpuscular emission from the solar flare of 1991 June 15: Continuous acceleraton of relativistic particles [PDF]
, 1993 Data on X-,γ-ray, optical and radio emission from the 1991 June 15 solar flare are considered. We have calculated the spectrum of protons that producesγ-rays during the gradual phase of the flare.

Towards advanced forecasting of solar energetic particle events with the PARASOL model
Journal of Space Weather and Space ClimateGradual solar energetic particle (SEP) events are generally attributed to the particle acceleration in shock waves driven by coronal mass ejections (CMEs). Space-weather effects of such events are important, so there has been continuous effort to develop

Acceleration of ions and electrons to near-cosmic ray energies in a perpendicular shock: The January 6, 1978 event [PDF]
Acceleration of energetic ions to approx 200 MeV and electrons to approx 2 MeV were detected by the Low Energy Charged Particle (LECP) instrument on Voyager 2 in association with a quasiperpendicular shock of theta sub Bn - 87.5 deg at 1.9 AU.
