| Abstract | The galactic nova, V2487 Oph 1998, was detected in both soft and hard X-rayswith XMM in 2000 and 2001. V2487 Oph showed an iron fluorescent line only 2.7years after its explosion, a clear signature of the very fast recovery ofaccretion. This was the first time that the recovery of a nova after itsexplosion was so-clearly seen in X-rays. However, details of emission and thelink with cataclysmic variables requires longer observations. Accurate timingand high resolution spectroscopy are essential to determine the main propertiesof the underlying cataclysmic variable in V2487 Oph, which is also the firstnova seen in X-rays prior (with ROSAT all-sky survey) and after its explosion. |

| 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. |
