Description We propose to use the RGS onboard XMM-Newton to measure the Hydrogen column density towards the X-ray binary 4U 1702-429. We will detect and model the Ne, Mg, Si, Fe and O absorption edges in the RGS spectra of the source to determine interstellar elemental abundances along the line of sight. We will convert these abundances to an equivalent hydrogen column density in order to (i) remove a source of large uncertainty in modeling the continuum source spectra, and (ii) measure the distance to the X-ray binary by employing a technique that compares the reddening of a source to that of red clump stars along the line of sight. Our ultimate goal is to combine the distance measurement with existing Type-I X-ray burst data to determine the mass and radius of the neutron star.

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.
