Title The changing photoionized plasma in the bright Low-Mass X-ray binary GX 13+1


DOI 10.5270/esa-23vyofi
Author Dr Maria Diaz Trigo
Description We propose five 10~ks XMM-Newton observations of GX13+1, the brightest low-mass X-ray binary (LMXB) which exhibits strong X-ray absorption features. Such features have been observed in a number of LMXBs and are identified with ions such as Fe XXV and Fe XXVI. GX13+1 is the best source to study the variations in the lines with the intensity of the source due to its both high and strongly variable luminosity. We will test whether the absorption lines detected in GX13+1 by XMM-Newton and Chandra are consistent with the presence of a highly-ionized absorber located around the accretion disk, similar to other LMXBs and study the changes of such absorber. This reveals dynamics of the disk wind, which commonly exists in high luminosity accretion-disk systems as galactic binaries and AGNs.

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.
