Description Detection of X-rays from classical novae in their post-outburst stages provides unique and crucial information about the explosion mechanism and the reestablishment of accretion. Soft X-rays reveal if a hot nuclear burning shell remains, whereas harder X-rays give diagnostics about the recovery of accretion and the magnetic or non magnetic character of the reborn cataclysmic variable. The unprecedented sensitivity of XMM-Newton will permit to deduce crucial parameters of the nova evolution: mass of the white dwarf, turnoff timescale, mass burned to helium, if burning is still on, and properties of the ejecta and-or the recovered accretion stream. We propose to observe 3 novae that exploded in 2006, to increase the still scarce data on recent novae.

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.
