Origin of the Unusual Composition of 3He-rich Solar Energetic Particles
The Astrophysical JournalWe examine ^3 He-rich solar energetic particles (SEPs) detected on 2023 October 24–25 by Solar Orbiter at 0.47 au. Measurements reveal that heavy-ion enhancements increase irregularly with mass, peaking at S.
