Description
We suggest a new way to understand cosmic ray proton and helium by introducing discrete local sources. The source of diffusion equation of cosmic ray propagation is set to be a point source given by delta function, contrary to conventional models which have continuous sources. We calculated the spectrum of proton and helium originated in close and young supernovas. By combining the solutions from discrete source and faraway continuous sources, we found cosmic ray propagation parameters that explain the discrepancy between the conventional models of cosmic ray and recent measurements of CREAM, PAMELA, and AMS-02 experiments.
