Statistical Relationship Between Long-duration High-Energy Gamma-Ray Emission and Solar Energetic Particles

Alessandro Bruno, Georgia A. de Nolfo, James M. Ryan +2

Large solar eruptions are often associated with long-duration gamma-ray emission extending well above 100 MeV. While this phenomenon is known to be caused by high-energy ions inter…

Energetic Proton Back-Precipitation onto the Solar Atmosphere in Relation to Long-Duration Gamma-Ray Flares

Adam Hutchinson, Silvia Dalla, Timo Laitinen +4

Gamma-ray emission during long-duration gamma-ray flare (LDGRF) events is thought to be caused mainly by >300 MeV protons interacting with the ambient plasma at or near the photo…

Physics of Solar Neutron Production: Questionable Detection of Neutrons from the 2007 December 31 Flare

Gerald H. Share, Ronald J. Murphy, Allan J. Tylka +3

Spacecraft observations in the inner heliosphere offer the first opportunity to measure 1-10 MeV solar neutrons. We discuss the physics of low-energy neutron production in solar fl…
