Variable Ion Compositions of Solar Energetic Particle Events in the Inner Heliosphere: A Field-line Braiding Model with Compound Injections
Fan Guo, Lulu Zhao, Christina M. S. Cohen +8
We propose a model for interpreting highly variable ion composition ratios in solar energetic particles (SEP) events recently observed by Parker Solar Probe (PSP) at a…
The reported durations of GOES Soft X-Ray flares in different solar cycles
Bill Swalwell, Silvia Dalla, Stephen Kahler +4
The Geostationary Orbital Environmental Satellites (GOES) Soft X-ray (SXR) sensors have provided data relating to, inter alia, the time, intensity and duration of solar flares sinc…
Coronal Sources of Impulsive Fe-Rich Solar Energetic Particle Events
Stephen Kahler, Donald Reames, Edward Cliver
We review recent work on 111 Fe-rich impulsive solar energetic ( 3 MeV/nuc) particle (SEP) events observed from 1994 to 2013. Strong elemental abundance enhancements scale wi…
Temperature of the Source Plasma for Impulsive Solar Energetic Particles
Donald V. Reames, Edward W. Cliver, Stephen W. Kahler
The steep power-law dependence of element abundance enhancements on the mass-to-charge ratios [A/Q] of the ions in impulsive solar energetic-particle (SEP) events causes these enha…
Large Solar Energetic Particle Events Associated with Filament Eruptions Outside of Active Regions
N. Gopalswamy, P. Makela, S. Akiyama +4
We report on four large filament eruptions (FEs) from solar cycles 23 and 24 that were associated with large solar energetic particle (SEP) events and interplanetary type II radio…
Variations in Abundance Enhancements in Impulsive Solar Energetic-Particle Events and Related CMEs and Flares
Donald V. Reames, Edward W. Cliver, Stephen W. Kahler
We study event-to-event variations in the abundance enhancements of the elements He through Pb for Fe-rich impulsive solar energetic-particle (SEP) events, and their relationship w…
