Cosmic ray antiprotons and the Single Source model

Abstract

In view of the fact that the AMS-02 instrument has recently been used to make preliminary observations of the ratio of the antiprotons (\-{P}) to protons (P) in the primary cosmic radiation we have returned to our idea of signatures of a local recent supernova. We find that at the present level of accuracy there is no inconsistency between our predictions for the \-{P}/P ratio to some hundreds of GeV using the preliminary observations.
