| Abstract | Detection of X-rays from classical novae in their post-outburst stages providesunique and crucial information about the explosion mechanism and the reestablishment of accretion. Soft X-rays reveal if H-nuclear burning is still on,whereas harder X-rays give diagnostics about the ejecta or the properties of thereborn CV. We have detected 3 interesting novae with our monitoring campaignwith XMM in AO6. V5116 Sgr (2005) and V5115 Sgr (2005) were still in thesupersoft X-ray phase, with V5116 Sgr displaying a puzzling temporal varibility.V2362 Cyg, on the contrary, had already turned-off, but the short effectiveexposure (due to high radiation) prevented to disentangle the origin of theemission. We propose new observations of these exciting post-novae. |

| 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. |
