GX340+00
We propose to observe the bright X-ray binary GX340+00 for 150 ks in order to explore the chemical and physical properties of the intervening interstellar dust. This source is the ideal candidate to study dense, never explored before, regions of the Galaxy. We will model the Si, S, Ca and Fe K-edges due to dust absorption. This will allow us to assess the silicate content (through Si and Fe) and its Ca inclusion in the core, as well as the sulphate content (through S and Fe). Additional science includes the study of the intrinsic highly ionized absorber/emitter.
