Sources of solar energetic particles. [PDF]
Philos Trans A Math Phys Eng Sci, 2019 Solar energetic particles are an integral part of the physical processes related with space weather. We present a review for the acceleration mechanisms related to the explosive phenomena (flares and/or coronal mass ejections, CMEs) inside the solar ...

Solar energetic particles and radio burst emission [PDF]
Journal of Space Weather and Space Climate, 2017 We present a statistical study on the observed solar radio burst emission associated with the origin of in situ detected solar energetic particles. Several proton event catalogs in the period 1996–2016 are used.

Solar Energetic Particles [PDF]
Lecture Notes in Physics, 2021 In a field overflowing with beautiful images of the Sun, solar energetic particle (SEP) events are a hidden asset, perhaps a secret weapon, that can sample the solar corona and carry away unique imprints of its most bizarre and violent physics.

Solar energetic particles in the inner heliosphere: status and open questions. [PDF]
Philos Trans A Math Phys Eng Sci, 2019 Solar energetic particle (SEP) events are related to both solar flares and coronal mass ejections (CMEs) and they present energy spectra that span from a few keV up to several GeV. A wealth of observations from widely distributed spacecraft have revealed

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 ...

On the Turbulent Reduction of Drifts for Solar Energetic Particles [PDF]
Astrophysical Journal, 2021 Particle drifts perpendicular to the background magnetic field have been proposed by some authors as an explanation for the very efficient perpendicular transport of solar energetic particles (SEPs).

Parker Solar Probe observations of helical structures as boundaries for energetic particles [PDF]
Monthly notices of the Royal Astronomical Society, 2021 Energetic particle transport in the interplanetary medium is known to be affected by magnetic structures. It has been demonstrated for solar energetic particles in near-Earth orbit studies, and also for the more energetic cosmic rays. In this paper, we

Solar Energetic Particles Produced during Two Fast Coronal Mass Ejections
Astrophysical Journal Letters, 2022 Two recent extremely fast coronal mass ejections (CMEs) are of particular interest. The first one originated from the southern hemisphere on 2021 October 28 and caused strong solar energetic particle (SEP) events over a wide longitude range from Earth ...

The Astrophysical Journal, 2023 Using numerical simulations, we analyze the time evolution of the pitch-angle distribution of 500 MeV and 1 GeV solar protons, released impulsively near the Sun, at 1 au. The numerical model solves the equations of motion of an ensemble of particles that

The Astrophysical Journal, 2023 Many aspects of solar energetic particles are not well understood, including their acceleration mechanism. There has been recent interest in the potential of energetic neutral atoms (ENAs) as remote probes of solar energetic particles (SEPs) and their ...
