Fig. 2.32.1. Dependence of a on fractal dimension of the medium dM under different assumptions on cross-section of CR particle interaction pxo from 0.01 up to 10. According to Lagutin et al. (2005).

2.32.4. Application to the problem of galactic CR spectrum formation

Possible candidates of the CR sources, located within 1 kpc from the Sun, with ages less than 4 x105 years, and the contribution of each source to total proton flux, are presented in Fig. 2.32.2. This Figure illustrates the contribution of each source to proton flux observed near the Sun, assuming that the output of protons from each supernova is the same and equal to
