Sources of primary cosmic rays
In the paper, a comparative primary cosmic rays (PCR) comparative analysis by
and the spectra of variable stars by periods is carried out in order to
establish the causes of irregularities in the spectrum of PCR by . The
study was performed using the public database of the KASCADE-Grande experiment
and GCVS and ZTF variable star catalogues. It has been suggested that the
acceleration of PCR to high and super-high energies occurs not only on the
shock waves of supernovae, but also in bursts of giants and super-giants. The
relationship between the periods of variable stars and the maximum energy
of the nuclei of PCRs generated by these types of stars is shown.
Irregularities in the PCR spectrum by are associated with the transition
from one dominant stars type to another as increases. The knee in the PCR
spectrum at is associated with a decrease in the contribution
of SRB variability stars and a further increase in the contribution of Mira
variable stars to the PCR flux. The bump in the PCR spectrum with a maximum at
, established in the KASCADE-Grande experiment, is formed by
giant stars and super-giants of the Mira and SRC variability
