Description Detection of X-ray emission from classical novae in their post-outburst stages provides unique information about the explosion mechanism. The analysis of the emission in soft X-rays enables a deep study of the remaining hot nuclear burning shell, whereas hard X-rays provide diagnostics of the internal or external shocks in the nova shells and-or about the recovery of accretion. The unprecedented sensitivity and spectral resolution of XMM instruments will permit to deduce crucial parameters of the nova evolution, i.e., mass of the white dwarf, turn-off timescale, mass burned into helium, if burning is still on, and properties of the ejecta and-or the recovered accretion stream. In this proposal we suggest the observation of 3 recent novae, which exploded in 2005.

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.
