Description | HD 15137 is an intriguing runaway O-type binary that offers a rare opportunity to explore the mechanism by which it was ejected from the open cluster of its birth. All of the evidence from optical spectra points to a compact companion in this system - except for the lack of hard X-ray emission detected from the system. HD 15137 is therefore a quiet HMXB candidate, too widely separated for the neutron star to accrete a significant mass of stellar winds and be detected as an X-ray binary. Therefore we propose observations with XMM-Newton, to occur at the time of periastron, that will detect the hard power law spectrum from a weakly accreting neutron star and reveal the evolutionary history of HD 15137. |

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. |
