The Detectability of Neon Fluorescence and Measurement of the Solar Photospheric Neon Abundance

Abstract

Monte Carlo calculations of the Ne K alpha line fluoresced by coronal X-rays and emitted near the temperature minimum region of the solar atmosphere have been employed to investigate the use of this feature to measure directly the solar photospheric Ne abundance. Although very weak, comparison with spectral line databases indicates that at plasma temperatures typical of the quiet Sun and cool active regions (
