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.

卫星实验中记录的质子和氦核的谱：宇宙射线扩散的非经典性质的指示

为了解释近十年来卫星实验中质子和氦核能谱的精确测量结果，提出了一个原始的非经典扩散模型。结果表明，在DAMPE和CALET实验中检测到的TeV能量范围内的光谱中断可以通过考虑距离地球150 - 200pc的一组tevatrons的贡献来解释，这些tevatrons的年龄为~ （4-6）× 105年。
