The Detectability of X-ray O and Ne Fluorescence Lines on the Sun and the Resolution of the Solar Model Problem

Jeremy Drake (SAO) , Barbara Ercolano (SAO), Jay Bookbinder (SAO)

The remarkable agreement between the observed solar oscillation spectrum and that predicted by solar models has been thrown into discord in recent years by evidence suggesting the photospheric C, N, O and Ne content has been overestimated by %. Monte Carlo calculations of the Ne K$T\sim 3\times 10^6$ K. We briefly describe the instrumental characteristics required to observe the lines and how they can be used to determine the photospheric Ne and O content and discriminate between competing solar abundance recommendations.
