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

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.
