| Abstract | We propose to obtain X-ray/UV observations of the 10.3 minute accreting binarysystem ES Cet. It is the brightest out of three recently identifiedultra-compact accreting binaries with orbital periods of 5-10 minutes. Thesesystems provide crucial insights into the physics of compact white dwarfbinaries that are the dominant gravitational wave sources in our galaxy, and theprogenitor population of Type Ia supernovae. The XMM-Newton lightcurves andspectra will be correlated with the strong optical variability, and compared tothe two other ultra-compacts and longer period AM CVn binaries. These X-raymeasurements will be crucial for establishing the nature of this enigmaticsystem, in particular the various accretion geometries that have been proposed. |

| 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. |
