|X-ray eclipse mapping of disc-accreting white dwarfs
|Dr Peter Wheatley
|We will apply the proven optical technique of eclipse mapping to X-ray observations of disc-accreting white dwarfs. Our pilot XMM-Newton study of a single system has proved that we can measure the extent of the shock-heated plasma around the compact object. The more sensitive observations proposed here will measure the shape of the eclipse ingress and egress - and thus the extent AND distribution of the X-ray emitting plasma - in two more systems. We will also study the coronal X-ray emission of the secondary star revealed during the eclipse.

|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.
