Secondary cosmic ray nuclei in the light of the Single Source Model

TL;DR

This paper discusses evidence for a local single source of cosmic rays, likely a supernova remnant, based on recent high-precision measurements of cosmic ray nuclei, electrons, positrons, and antiprotons, supporting the Single Source Model.

Contribution

It provides new analysis confirming the Single Source Model using recent cosmic ray data and estimates properties of the proposed local supernova remnant.

Findings

Evidence supports a local single source of cosmic rays.

Measurements of boron-to-carbon ratio and lithium spectrum are consistent with the model.

Properties of the supernova remnant are estimated.

Abstract

Evidence for a local 'Single Source' of cosmic rays is amassing by way of the recent precise measurements of various cosmic ray energy spectra from the AMS-02 instrument. To observations of individual cosmic ray nuclei, electrons, positrons and antiprotons must now be added the determination of the boron-to-carbon ratio and the energy spectrum of lithium to 2000 GV with high precision. Our analysis leads us to claim that, with certain assumptions about the propagation in the Galaxy, the results confirm our arguments regarding the presence of a local single source, perhaps, a supernova remnant (SNR). An attempt is made to determine some of the properties of this SNR and its progenitor star.
