SUMMARY:The Dirt on Dust: An X-ray Perspective\, Astronomy Colloquium\
 , Professor Julia  Lee\, Harvard University
DESCRIPTION:The compositional make-up of interstellar dust and the rel
 ative abundances of chemical elements in astrophysical environments ar
 e not well understood\, despite good progress. Since dust is a primary
  repository of the interstellar medium\, and is responsible for the ch
 emical evolution of stars\, planets\, and life itself\, it has a profo
 und effect on many areas of astrophysical research from cosmology to s
 tar and planet formation. High spectral resolution X-ray instruments o
 n powerful X-ray satellites (e.g. Chandra\, XMM-Newton\, Suzaku) point
 ed  through dust and gas  at bright black hole and neutron star system
 s can be used to study dust and intervening material in unique ways.  
 With the  new subfield of High Energy Condensed Matter Astrophysics as
  its goal\, I will discuss a new technique for determining  dust compo
 sition and depletion using X-rays\, initial progress\, and future pros
 pects.<br><br>
