Spectrum and Chemical Composition of CRs Accelerated in SNRs

Spectrum and chemical composition of cosmic rays accelerated in supernova remnants are studied on a basis of kinetic approach. The cosmic ray transport equation with the Bohm diffusion coefficient has been numerically solved self-consistently with gas dynamic equations for the underlying flow. Comparison with observational results gives some indications that galactic cosmic rays are produced by supernovae shocks which expanded in the relatively low temperature partially ionized interstellar medium.
