Description We propose to observe the X-ray halo and spectrum of the high mass X-ray binary X Per. The X-ray halo is formed by scattering from dust grains along the line of sight (LOS), which appears to intersect only 1-2 molecular clouds. These clouds likely contain nearly all the material in the LOS. Unlike many other X-ray halo observations, the low-absorption high-latitude sightline is well-characterized from absorption spectroscopy done with HST and FUSE. This halo measurement will allow us to place tight constraints on the clouds. positions and the dust size distribution in the clouds. In addition, the X-ray spectrum of X Per is quite unusual for a HMXB, and the RGS spectrum will measure or put limits on emission lines suggested by the Chandra-LETG data.

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.
