Description An ultra-compact X-ray binary (UCXB) candidate with potentially the shortest known orbital period of 10.2 minutes was serendipitously discovered in the Galactic Bulge. Its only available X-ray spectra from XMM, and radio-IR observations suggest that the source may be the first direct impact NS binary with no accretion disk or (less likely) an intermediate polar. The proposed NuSTAR+XMM observations will confirm the period for a NS spin, and identify the source by a combination of broad-band X-ray spectroscopy and Fe line diagnostics. Given its short orbital period, the source may be one of the few UCXBs detectable by the future LISA GW observatory.

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.
