Charge transfer X-rays in solar and stellar flares

摘要

Most of the energy in a solar flare, and presumably a stellar flare as well, takes the form of a power law of energetic particles. The energetic electrons produce a bremsstrahlung continuum, while the most energetic nuclei produce gamma-rays. Nuclei around 1 MeV/AMU can produce X-rays during and after charge transfer with neutrals. This paper predicts the fluxes for some prominent X-ray lines and compares them to existing spectra (? 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
