Abstract
Aims.A model to describe cosmic ray spectra in the energy region from 1010
to 1017 eV is suggested based on the assumption that Galactic cosmic ray flux
is a mixture of fluxes accelerated by shocks from nova and supernova of
different types.
Methods.We analyze recent experimental data on cosmic ray spectra obtained in direct measurements
above the atmosphere and data obtained with ground extensive air shower (EAS) arrays.
Results.The model of the three classes of cosmic ray sources is consistent with
direct experimental data on cosmic ray elemental spectra and gives a smooth transition
from the all particle spectrum measured in the direct experiments to the all particle spectrum
measured with EAS.
Key words: cosmic rays -- ISM: supernova remnants -- ISM: abundances
