Detection of X-ray emission from classical novae in their post-outburst stageswould provide crucial information about the nova phenomenon. The analysis ofthe emission in soft X-rays, together with that in the UV range, would enableto do a deep study of the remaining hot nuclear burning shell, whereas the hardX-ray emission would provide diagnostics of the internal or external shocksin the nova shells. The unprecedented sensitivity and spectral resolution ofXMM instruments will permit to deduce crucial parameters of the nova evolution(i.e., mass of the white dwarf, turn-off time scales, mass burned into helium).In this proposal we suggest the observation of 7 recent classical novae, whichhave large possibilities to be detectable, at 3 different epochs.

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.
