It is well known that diffuse gamma-rays are produced by collisions between Galactic cosmic rays and interstellar matter (Hayakawa−Hutchinson−Morrison hypothesis). We estimate the contribution of high energy protons produced by stellar flares to the diffuse component of Galactic gamma-rays. Each star in the Galaxy regularly produces flares that generate high energy protons in the energy range from 100 MeV to 1 TeV. These protons are a likely source of cosmic rays. We estimate that the Galactic bulge can constantly generate 2.7×10 A of high energy proton current.
