The Cosmic-Ray Source Composition as a Probe of the Acceleration Mechanisms. I. General
Abstract
A comparison is made between cosmic ray source (CRS) and local galactic (LG) elemental and isotopic compositions with realistic error bars. The possible roles of nucleosynthesis and atomic processes in shaping the CRS composition are discussed. It is found that the major fraction of the CR nuclei should originate in a medium of normal LG composition, in which atomic selection effects seem to operate on a singly ionized gas. In addition, the possible origin of the Ne-22 rich component of galactic cosmic rays are discussed. The only plausible source is the explosive processing of H-rich envelopes of novae and supernovae.
