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.

Formation of the Injection Function of Solar Energetic Particles in Gradual Events [PDF]
The Astrophysical Journal, 2023 We present a model for solar energetic particle injection into interplanetary space in gradual events, in which particle acceleration occurs in a limited region of the solar atmosphere.

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.
