Abstract

An original nonclassical diffusion model was proposed for the astrophysical interpretation of the results of precision measurements of the energy spectra of protons and helium nuclei in satellite experiments in the last decade. It was shown that the breaks in the spectra in the TeV energy range that were detected in the DAMPE and CALET experiments can be explained by taking into account the contributions of a group of tevatrons located at a distance of 150–200 pc from the Earth and having an age of ∼(4–6) × 105 years.
