Cosmic-ray interactions with the Sun using the fluka code

The interactions of cosmic rays with the solar atmosphere produce secondary particles which can reachthe Earth. In this work, we present a comprehensive calculation of the yields of secondary particles such asgamma-rays, electrons, positrons, neutrons, and neutrinos performed with the FLUKA code. We alsoestimate the intensity at the Sun and the fluxes at the Earth of these secondary particles by folding theiryields with the intensities of cosmic rays impinging on the solar surface. The results are sensitive to theassumptions on the magnetic field nearby the Sun and to the cosmic-ray transport in the magnetic field inthe inner Solar System.
