Secondary Cosmic Ray Nuclei in the Light of the Single Source Model

TL;DR

This paper presents evidence supporting a local 'Single Source' of cosmic rays, based on recent high-precision measurements of various cosmic ray spectra, suggesting a nearby supernova remnant as the source.

Contribution

It provides new analysis linking recent cosmic ray data to a local single source, possibly a supernova remnant, under specific propagation assumptions.

Findings

Supports the existence of a local single source of cosmic rays

Confirms the presence of a nearby supernova remnant as the source

Provides estimates of properties of the SNR and its progenitor star

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 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.
