WebJan 26, 2024 · We give a brief review of the origin and acceleration of cosmic rays (CRs), emphasizing the production of CRs at different stages of supernova evolution by the first-order Fermi shock acceleration mechanism. We suggest that supernovae with trans-relativistic outflows, despite being rather rare, may accelerate CRs to energies above … WebThe local sources of cosmic rays consist of the following two kinds; one is supernovae at which about 10 −6 of ejected particles are accelerated to cosmic ray energy and the other is supergiant and red giant stars at which the above ratio seems to be 10 −8 – 10 −7. The chemical composition of cosmic rays from the latter is equal to that ...
