Sources of solar energetic particles [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 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 corona.

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 ...

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

On the Onset Delays of Solar Energetic Electrons and Protons: Evidence for a Common Accelerator
The Astrophysical Journal, 2023 The processes responsible for the acceleration of solar energetic particles (SEPs) are still not well understood, including whether SEP electrons and protons are accelerated by common or separate processes. Using a numerical particle transport model that

Analysis of SEP Events and Their Possible Precursors Based on the GSEP Catalog
The Astrophysical Journal Supplement Series, 2023 Solar energetic particle (SEP) events are one of the most crucial aspects of space weather. Their prediction depends on various factors including the source solar eruptions such as flares and coronal mass ejections (CMEs).

Dispersive Suprathermal Ion Events Observed by the Parker Solar Probe Mission
The Astrophysical Journal Letters, 2023 During Encounter 11, Parker Solar Probe observed a low-energy dispersive ions event of solar origin. The event was observed in the SPAN-I and IS⊙IS EPI-Lo sensors.

From the Sun’s south to the north pole – Ulysses COSPIN/LET composition measurements at solar maximum [PDF]
Annales Geophysicae, 2003 Based on elemental abundance ratios derived from the Ulysses COSPIN/LET measurements, we classified the energetic particle populations during and after the socalled Fast Latitude Scan – the time period during which the Ulysses spacecraft traveled
