We investigate gamma-ray emission in the impulsive phase of solar flares and the detectability of nonthermal signatures from protostellar flares. Energetic solar flares emit high-energy gamma rays of GeV energies. but their production mechanism and emission site are still unknown. Young stellar objects. https://www.alarecre.com/NHL-Vegas-Golden-Knights-Black-Background-iPhone-14-Plus-Skin-p42149/
