A Perspective on Solar Energetic Particles

Frontiers in Astronomy and Space Sciences, 2022
The author has been fortunate to observe and participate in the rise of the field of solar energetic particles (SEPs), from the early abundance studies, to the contemporary paradigm of shock acceleration in large SEP events, and element abundance ...

Shock Propagation and Associated Particle Acceleration in the Presence of Ambient Solar-Wind Turbulence

Frontiers in Astronomy and Space Sciences, 2021
The topic of this review paper is on the influence of solar wind turbulence on shock propagation and its consequence on the acceleration and transport of energetic particles at shocks.

Current status and possible extension of the global neutron monitor network

Journal of Space Weather and Space Climate, 2020
The global neutron monitor network has been successfully used over several decades to study cosmic ray variations and fluxes of energetic solar particles. Nowadays, it is used also for space weather purposes, e.g. alerts and assessment of the exposure to

Ulysses COSPIN observations of cosmic rays and solar energetic particles from the South Pole to the North Pole of the Sun during solar maximum [PDF]

Annales Geophysicae, 2003
In 2000–2001 Ulysses passed from the south to the north polar regions of the Sun in the inner heliosphere, providing a snapshot of the latitudinal structure of cosmic ray modulation and solar energetic particle populations during a period near ...

Transmission and Emission of Solar Energetic Particles in Semi-transparent Shocks. [PDF]

, 2014
While major solar energetic particle (SEP) events are associated with coronal mass ejection (CME)-driven shocks in solar wind, accurate SEP measurements reveal that more than one component of energetic ions exist in the beginning of the events.

Energy Spectrum of Solar Energetic Electron Events over 25 Years

The Astrophysical Journal, 2023
We investigate the peak flux energy spectrum of 458 solar energetic electron (SEE) events with a clear velocity dispersion detected at energies from ≤4.2 to ≥108 keV by Wind/3DP from 1994 December through 2019 December, utilizing a pan-spectrum fitting ...

Synthesis of 3-D coronal-solar wind energetic particle acceleration modules [PDF]

, 2014
1. Introduction Acute space radiation hazards pose one of the most serious risks to future human and robotic exploration. Large solar energetic particle (SEP) events are dangerous to astronauts and equipment.

The Isotopic Composition of Solar Energetic Particles [PDF]

, 2000
Since the launch of ACE in August 1997, the Solar Isotope Spectrometer (SIS) has observed 11 large solar particle events in which elemental and isotopic composition was determined over a large energy range. The composition of these events has raised many

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.
