We propose to observe five quiescent, accreting novae, 152 to 2 years after theoutburst. We will explore the role of the mass transfer rate, white dwarf massand magnetic fields in shaping the evolution and the characteristics of thethermonuclear flashes, in targets that were well monitored in outburst. Thetheory of explosive hydrogen burning in a shell on massive white dwarfs is thebasis for understanding novae and type Ia supernovae, but many observationalparameters are unknown. These observations will provide the key for betterunderstanding nova evolution. They will also be a legacy of XMM-Newton, andgroundwork for programs of future X-ray observatories.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
