The Origin of Present Day Cosmic Rays: Fresh SN Ejecta or Interstellar Medium Material ? I Cosmic Ray Composition and SN Nucleosynthesis. A Conflict with the Early Galactic Evolution of Be ?
J. P. Meyer, D. C. Ellison
The composition of present day cosmic rays (CRs) is inconsistent with a significant acceleration of SN ejecta material (even with a preferential acceleration of ejecta grain materi…
