Abstract

Interactions of cosmic-ray nuclei is the most well-understood contribution to the observed positron flux on Earth. Various scenarios have been proposed, including sources in the spiral arms of the galaxies and nearby isolated sources, which can contribute to the measured flux. In our work we focus on sources such as the gamma-ray novae which can contribute to the observed positron flux, although sub-dominant to the supernova remnants or pulsar-wind nebulae overall, but crucial in the 10s of GeV energy range.
