Sources of Primary Cosmic Rays at an Energy of ~100 PeV
A comparative analysis of the spectra of primary cosmic rays (PCR) over Е0 and the spectra of variable stars over the periods is performed with for the purpose of determining the causes of irregularities in the PCR spectrum over Е0. The dependence between periods of variable stars and the maximum energy Е0 of PCR nuclei generated by such star types is shown. The irregularities in the PCR spectrum by Е0 are associated with the transition of one dominant star type to another with increasing Е0. The knee in the PCR spectrum at Е0 = 3–5 PeV is associated with a decrease in the contribution of SRB variability stars and the further increase in the contribution of stars of Myra-type variability to the PCR flux. The bump in the PCR spectrum with a maximum at Е0 = 80 PeV is formed by giant and supergiant stars of the Myra-type and SRC variabilities.
