Description We will apply the proven optical technique of eclipse mapping to X-ray
observations of disc-accreting white dwarfs. Our previous XMM-Newton studies
have demonstrated the value of this technique by allowing us to measure the
extent of the shock-heated plasma around the compact objects in OY Car and HT
Cas. In this proposal we request observations of the only other bright
well-studied eclipsing dwarf nova, Z Cha. We will measure the duration and the
shape of the eclipse ingress and egress, and thus determine the extent and
distribution of the X-ray emitting plasma. We will also study the coronal X-ray
emission of the secondary star revealed during the eclipse.

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.
