|Title||Monitoring the decay of RS Ophiuchi|
|Author||Dr Marina Orio|
|Description||RS Ophiuchi is a recurrent nova and a symbiotic binary system that is thought to host a very massive white dwarf on the verge of the Chandrasekhar limit, and be a type Ia supernova candidate. In February of this year, RS Ophiuchi had an outburst attributed to a thermonuclear runaway and has been monitored at all wavelength, including X-rays with RXTE, Swift, Chandra and XMM-Newton. XMm-Newton is the only telescope that is best suited to follow the decay and return to quiescence of this interesting system, completing the puzzling and in many ways revolutionary picture offered in outburst.|

|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.
