Abstract

We present a theoretical model and database designed to provide analysis of astrophysical X-ray absorption fine structure (XAFS). The model includes spherical wave corrections and multiple-scattering contributions to the modification of the X-ray absorption coefficient. The model and database provide the basis for the astrophysical XAFS analysis (AXA) tool, which may be used to analyze properties of interstellar grains and molecules from high-resolution X-ray spectra expected to be observed by future satellite missions (e.g., the Advanced X-ray Astrophysics Facility).
