Description Classical Novae are strong X-ray emitters during the first days-months after outburst. Their X-ray spectrum shows two components which evolve separately: a hard one, caused by shocks in the ejecta, appearing a few days-weeks after the outburst, and a soft one, due to residual Hydrogen burning on the surface of the WD, which becomes visible a few months later. The purpose of this proposal is to perform XMM observations of four recent, bright classical novae 1-2 years after the outburst, when both spectral components should be visible. We intend to observe each object two times six months apart, to study the nature and variability of the spectral components, to estimate typical timescales, and to link the observed behaviour to the characteristics of the individual systems.

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.
