Description The outbursts of novae are driven by a thermonuclear runaway at the base of an accreted shell. Soft X-ray emission resulting from high surface temperatures on the WD after outburst are expected, but seldom observed (SSS phase). Some novae enter the SSS phase within the first year after outburst, and quickly turn off thereafter (the very fast ONeMg novae). Others (e.g., slow novae) are delayed years after outburst before entering the SSS stage, which then lasts many years. ROSAT detected only 3 novae in their SSS state; XMM has observed 5, 3 which have SSS spectrums. Insight into the diversity and evolution of novae can be gained by determining when (or if) the SSS stage begins, when turnoff occurs, and how this relates to composition and the mass of the WD.

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.
