We propose a 100 ks observation of the V407 Cyg, a symbiotic star which recentlyexperienced its first recorded nova outburst. A new X-ray observation of thesystem in quiescence will allow us to establish the timescales over whichaccretion is re-established after the nova outburst, and if it has, the rate atwhich material is accreted by the white dwarf. We will also study the long termevolution of the nova ejecta. Characterizing the accretion process andinteraction of the ejecta with the companion wind is a key part of understandingtype Ia supernovae like SN 2002ic, which exhibit evidence of strongcircumstellar interaction.

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.
