Description
The observed electromagnetic spectrum of the quiet Sun extends up to hundreds of GeVs. Indeed, the Sun is a recently-known gamma-ray source also in its quiescent state. The high-energy quiescent emission is supposed to originate from interactions of Galactic cosmic rays with the solar surface and its surroundings.
We provide an overview of our current knowledge on theoretical expectations and present observations of the steady-state emission from the Sun.
