X-ray Astromineralogy

To understand how the elements cycle from stars to planets, we must understand the chemical composition, sizes and shapes of interstellar dust, which affects the physics of galaxies, star and planet formation. X-ray observations provide the most direct means for astromineralogy through X- ray absorption fine structure imprinted by dust onto the spectra of bright Galactic X-ray sources. I'll review the latest results in astromineralogy and our work on connecting interstellar dust with suspected extra-solar grains collected in our own Solar System. Finally, I'll show how the recently launched XRISM space mission is contributing to questions in astromineralogy.
