|Title||A bright nova in outburst|
|Author||Dr Marina ORIO|
|Description||We propose a TOO program to observe a classical or recurrent nova in outburst, if it is observed to turn into a luminous X-ray source with Swift. Our aims are: a) to constrain the mass, temperature and chemical composition of the white dwarf by analyzing the spectrum, b) to correlate spectral and temporal variability during the nuclear burning phase, and c) if the shell is very X-ray bright, to use the RGS to explore wind mass loss in a recurrent nova. The proposed study is important not only for nova-CV theory, but also for understanding hydrogen burning in shell in supernova Ia progenitors.|

|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.
