|Title||X-ray and UV Photometry of the Partially Eclipsing Dwarf Nova V893 Sco|
|Author||Dr Koji Mukai|
|Description||We have recently performed a Suzaku X-ray observation of the short period dwarf nova V893 Sco and discovered it to be partially eclipsing at X-ray energies, the first such event to be discovered among the class of dwarf novae. However, the eclipse phase was only observed 2.5 times in the short 20 ksec Suzaku observation. Here we propose a longer XMM-Newton observation to observe 8 full eclipses using the EPIC cameras, complemented by simultaneous UV photometry using the OM, to determine the location and measure the extent of the X-ray emission region in dwarf novae.|

|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.
