| Description | UX UMa is the X-ray brightest eclipsing nova-like variable. This observation will enable us to compare the X-ray behaviour of a system in a permanent high accretion state with that of an SU UMa system in superoutburst. The superout burst targets are not included here because of their need for TOO status. Many of the scientific aims are common to the two proposals, but they are not .associated. The questions to be addressed are: What is the source of X-ray emission in the high mass accretion rate regime Is the extended X-ray source a wind or static corona Can we solve the UV .iron curtain conundrum. Can we demonstrate for the first time that the secondary star is a significant contributor to the X-ray flux by detecting a secondary star 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. |
