| Abstract | We propose five 10virgulks XMM-Newton observations of GX13+1, the brightest low-massX-ray binary (LMXB) which exhibits strong X-ray absorption features. Suchfeatures have been observed in a number of LMXBs and are identified with ionssuch as Fe XXV and Fe XXVI. GX13+1 is the best source to study the variations inthe lines with the intensity of the source due to its both high and stronglyvariable luminosity. We will test whether the absorption lines detected inGX13+1 by XMM-Newton and Chandra are consistent with the presence of ahighly-ionized absorber located around the accretion disk, similar to otherLMXBs and study the changes of such absorber. This reveals dynamics of the diskwind, which commonly exists in high luminosity accretion-disk systems as galactic binaries and AGNs. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
