|Title||An XMM-Newton view of the earliest X-ray evolution of a nova in outburst.|
|Author||Dr Thomas Nelson|
|Description||We request weekly monitoring of a new classical nova over the first two months of the outburst, with the goal of obtaining the most detailed X-ray observations to date of this phase of the outburst evolution. These new observations will allow us to constrain the onset time of the early X-ray emission and to track any changes in this emission as the outburst evolves. We will investigate the origin of these X-rays (internal shocks or interaction with an external medium) through spectral modeling, and comparison with complementary radio and optical observations. Understanding the physics of mass loss from novae, both in outburst and during the accreting phase, is crucial for determining the long term evolution of the white dwarfs in these 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.
