The Physics of Solar Energetic Particles

Donald V Reames

Solar energetic particles (SEPs) are produced in two fundamental ways: at magnetic reconnection sites in solar jets and at collisionless shock waves driven by fast coronal mass eje…

Solar Particle Acceleration

Donald V. Reames

High-energy particles may be accelerated widely in stellar coronae; probably by the same processes we find in the Sun. Here, we have learned of two physical mechanisms that dominat…

Seeds and Sequences of Element Abundances in Solar Energetic Particle Events

Donald V. Reames

Solar energetic particles (SEPs) in the small "impulsive" events, primarily accelerated during magnetic reconnection in solar jets, have strong enhancements of the abundances of in…

Element Abundances and the Physics of Solar Energetic Particles

Donald V. Reames

Acceleration and transport of solar energetic particles (SEPs) causes their abundances, measured at constant velocity, to be enhanced or suppressed as a function of each ion's magn…

Review and Outlook of Solar-Energetic-Particle Measurements on Multispacecraft Missions

Donald V. Reames

The earliest evidence on spatial distributions of solar energetic particles (SEPs) compared events from many different source longitudes on the Sun, but the early Pioneers provided…

How Do Shock Waves Define the Space-Time Structure of Gradual Solar Energetic Particle Events?

Donald V. Reames

We revisit the full variety of observed temporal and spatial distributions of energetic solar protons in "gradual" solar energetic-particle (SEP) events resulting from the spatial…
