Solar Orbiter SEP Dropout during a Magnetic Cloud with Evidence for Strong Connectivity Gradients

Radoslav Bucik, Raul Gomez-Herrero, Samuel T. Hart +2

We analyze an impulsive solar energetic particle (SEP) event observed by Solar Orbiter at 0.93 au on 2022 December 24 that exhibits a pronounced intensity dropout between approxima…

Helium-3 Enrichment in Gradual Solar Energetic Particle Events: Evidence for Jet-Supplied Seed Population

R. Bucik, S. T. Hart, M. A. Dayeh +3

Enhancements in 3He abundance, a characteristic feature of impulsive solar energetic particle (ISEP) events, are also frequently observed in gradual SEP (GSEP) events. Understandin…

Polytropic Behavior in Corotating Interaction Regions: Evidence of Alfvénic Heating

M. A. Dayeh, M. J. Starkey, G. Livadiotis +5

Corotating Interaction Regions (CIRs) are recurring structures in the solar wind, characterized by interactions between fast and slow solar wind streams that compress and heat plas…

Origin of 3He abundance enhancements in gradual solar energetic particle events

Radoslav Bucik, Samuel T. Hart, Maher A. Dayeh +3

We examined the origin of 3He abundance enhancement in 23 high-energy (25-50 MeV) solar proton events that coincide with 3He-rich periods detected by ACE ULEIS in 1997-2021. In sev…
