| Description | ASCA and BeppoSAX observations of a number of ultra-compact (P<1hr) X-ray binaries have revealed two possible spectral differences compared to other LMXRB systems. These are (1) the presence of a discrete feature near 0.7 keV (attributed to Ne) and (2) their best-fit parameter values when fit with a disk-blackbody and Comptonized continuum. We wish to clarify and extend the emerging picture of a spectral signature for the ultra-compact systems using XMM--Newton. The proposed observations will allow a clear confirmation of such a signature which will, in turn, allow the nature of a LMXRB to be determined from its spectral characteristics. |

| 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. |
