Solar wind turbulence: Connections with energetic particles
New Astronomy, 2021 Abstract For the solar wind, a wealth of observational evidence indicates that turbulence is an important dynamical process for velocity (v), magnetic (b), and other related fluctuations at MHD (fluid) scales. Here we review such observations and turbulence features, including discussion of when wave or turbulence descriptions can (or cannot) explain

Experimental Observation Of Energetic Ions Accelerated By Three-Dimensional Magnetic Reconnection In A Laboratory Plasma [PDF]
, 2002 Magnetic reconnection is widely believed responsible for heating the solar corona as well as for generating X-rays and energetic particles in solar flares. On astrophysical scales, reconnection in the intergalactic plasma is a prime candidate for a local

Temporal Evolution of Solar Energetic Particle Spectra [PDF]
Solar Physics, 2016 During solar flares and coronal mass ejections, solar energetic par- ticles (SEPs) may be released into the interplanetary medium and near-Earth locations. The energy spectra of SEP events at 1 AU are typically averaged over the entire event or studied in a few snapshots.

Acceleration of solar wind particles by traveling interplanetary shocks [PDF]
, 2019 The acceleration of thermal solar wind protons at spherical interplanetary shocks driven by coronal mass ejections is investigated. The solar wind velocity distribution is represented using $\kappa$-functions, which are transformed in response to ...

THE EFFECT OF TURBULENCE INTERMITTENCE ON THE EMISSION OF SOLAR ENERGETIC PARTICLES BY CORONAL AND INTERPLANETARY SHOCKS [PDF]
Major solar energetic particle events are associated with shock waves in solar corona and solar wind. Fast scattering of charged particles by plasma turbulence near the shock wave increases the efficiency of the particle acceleration in the shock, but ...

Space Climate and Solar Energetic Particles [PDF]
Iranian Journal of Astronomy and AstrophysicsIn this paper, we investigate the effect of solar corona magnetic activities during 11-year periods and energetic particles on global warming. According to atmospheric changes during the past years, the relationship between these two issues should be ...

Solar Energetic Particle Events: Phenomenology and Prediction [PDF]
Space Science Reviews, 2003 Solar energetic particle events can cause major disruptions to the operation of spacecraft in earth orbit and outside the earth’s magnetosphere and have to be considered for EVA and other manned activities. They may also have an effect on radiation doses received by the crew flying in high altitude aircraft over the polar regions.

Revisiting empirical solar energetic particle scaling relations
Astronomy & Astrophysics, 2023 Aims. The possible influence of solar superflares on the near-Earth space radiation environment are assessed through the investigation of scaling laws between the peak proton flux and fluence of solar energetic particle (SEP) events with the solar flare soft X-ray peak photon flux. Methods. We compiled a catalog of 65 well-connected (W20-90) SEP events

New views of solar energetic particles from the Advanced Composition Explorer [PDF]
, 2000 Since its launch in August 1997, the Advanced Composition Explorer has been measuring the elemental, isotopic, and ionic charge-state composition of solar energetic particles with three new, high-resolution instruments (SEPICA, SIS, and ULEIS).
