Description We propose to observe the bright low-mass X-ray binary 4U 1735-444 with XMM-Newton RGS for 80 ks. We will obtain a high quality spectrum with several strong features due to the interstellar medium (ISM) in the line of sight of this source. The high resolution, large effective area and broad band coverage of RGS will allow us to resolve absorption structures from neutral and ionized species of C, N, O, Fe, Ne and Mg. Our proposed observation will provide the best simultaneous analysis of the ISM Fe and O so far. The collisional- or photo-ionized nature of the warm and hot ionized phases of the ISM will be constrained. The identification of interstellar minerals will determine the ISM composition and abundances, which are r^ant for the star formation.

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.
