Evidence that SOL2012-06-03 Late Phase Rays are Produced by 300 MeV Protons from CME-Shock Acceleration of Suprathermals from the Flare
Gerald H. Share, Ronald J. Murphy
A recent paper on SOL2012-06-03 reported the detection for the first time of two distinct phases of 100 MeV -radiation indicating separate acceleration processes. But such tw…
-Ray Lines -- Signatures of Nucleosynthesis, Cosmic Rays, Positron Annihilation, and Fundamental Physics
Thomas Siegert, Francesca Calore, Pierre Jean +6
The nuclear -ray lines in the MeV range of the electromagnetic spectrum hold a vast variety of astrophysical, particle-physical, and fundamental physical information that is oth…
Solar Gamma-Ray Evidence for a Distinct Population of 1 MeV Flare-Accelerated Electrons
Gerald H. Share, Ronald J. Murphy, Brian R. Dennis +1
Significant improvements in our understanding of nuclear -ray line production and instrument performance allow us to better characterize the continuum emission from electrons at…
Evidence for a Coronal Shock Wave Origin for Relativistic Protons Producing Solar Gamma-Rays and Observed by Neutron Monitors at Earth
Athanasios Kouloumvakos, Alexis P. Rouillard, Gerald H. Share +4
We study the solar eruptive event on 2017 September 10 that produced long-lasting 100 MeV -ray emission and a ground level enhancement (GLE72). The origin of the high-energy…
Characteristics of Sustained >100 MeV Gamma-ray Emission Associated with Solar Flares
G. H. Share, R. J. Murphy, A. K. Tolbert +4
We characterize and provide a catalog of thirty >100 MeV sustained gamma-ray emission (SGRE) events observed by Fermi LAT. These events are temporally and spectrally distinct from…
The magnetic connectivity of coronal shocks from behind-the-limb flares to the visible solar surface during -ray events
I. Plotnikov, A. P. Rouillard, G. H. Share
Context. The observation of >100 MeV γ-rays in the minutes to hours following solar flares suggests that high-energy particles interacting in the solar atmosphere can be stored and…
