GeV Particles in the Inner Heliosphere
Abstract
The Fermi/LAT observations of GeV solar gamma rays, both from flares and from two distingishable quiet-Sun sources, make the cosmic-ray environment of the inner heliosphere topically interesting. The Parker Solar Probe and Solar Orbiter will explore this territory in new ways. We discuss recent developments related both to flare/CME processes and to the quiet Sun, noting that the solar equivalent of the Stoermer theory remains to be worked out. We describe extensive shower products from the GeV particles in the solar atmosphere (and in the atmosphere of Venus) as another item of interest.
