DRIFT-INDUCED DECELERATION OF SOLAR ENERGETIC PARTICLES [PDF]

The Astrophysical Journal, 2015
We investigate the deceleration of Solar Energetic Particles (SEPs) during their propagation from the Sun through interplanetary space, in the presence of weak to strong scattering in a Parker spiral configuration, using relativistic full orbit test particle simulations.

A Living Catalog of Parker Solar Probe IS⊙IS Energetic Particle Enhancements

The Astrophysical Journal Supplement Series, 2023
Energetic charged particles are pervasive throughout the heliosphere with contributions from solar energetic particle events, stream and corotating interaction regions, galactic cosmic rays, anomalous cosmic rays, and suprathermal ions.

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.

Time distributions of solar energetic particle events: Are SEPEs really random?

, 2009
Solar energetic particle events (SEPEs) can exhibit flux increases of several orders of magnitude over background levels and have always been considered to be random innature in statistical models with no dependence of any one event on the occurrence of ...

Yield Function of the DOSimetry TELescope Count and Dose Rates Aboard the International Space Station

Space Weather, 2021
The Earth is constantly hit by energetic particles originating from galactic sources. The flux of these particles is altered by the magnetized solar wind in the heliosphere and the Earth's magnetic field.

3He-Rich Solar Energetic Particles: Solar Sources [PDF]

Space Science Reviews, 2020
3He-rich solar energetic particles (SEPs), showing up to a 10,000-fold abundance enhancement of rare elements like 3He or ultra-heavy nuclei, have been a puzzle for more than 50 years. One reason for the current lack of understanding of 3He-rich SEPs is the difficulty resolving the source regions of these commonly occurring events.
