|Title||Towards an X-ray-defined model for the chemistry of interstellar dust|
|Author||Dr Elisa Costantini|
|Description||We propose to observe the bright X-ray binary GX 9+9 as an ideal target to investigate the dust chemistry in the diffuse interstellar medium. X-rays have recently probed an invaluable tool in order to directly access the chemical composition of dust in the Galactic plane. High resolution spectroscopy with XMM-Newton is essential to study the diffuse dust component by studying the oxygen and iron edges in the soft X-ray band. With this proposal we aim at defining a general model for the chemistry of the diffuse interstellar dust.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
