Description Iron lines have now been detected in about half a dozen neutron-star accreting X-ray binaries. These lines can be used to set tight constrains on the accretion disk geometry and on the radius of the neutron star. We have recently shown that simultaneous XMM-Newton-RXTE and Chandra-RXTE observations appear to contradict previous works. Here we propose to observe a NS with XMM-Newton seven times for 25virgulks, simultaneously with some of those RXTE observations. Our program will sample a wide range of inner disk radii. This program requires both XMM-Newton and RXTE observations. Since 2009 may be the last year of operations of RXTE, this program can only be done now.

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.
