The runaway O-type binaries HD 14633 and HD 15137 were likely ejected from thecluster of their birth by supernovae explosions in close binaries. Neither staris a known X-ray source, but they likely contain neutron stars and may be weakstellar wind accretion systems. Hence the two binaries have been classified asquiet HMXBs. We propose observations with XMM-Newton that will detect the hardpower-law spectrum from accreting or quiescent neutron star companions andreveal their evolutionary history.

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.
