|Title||Transient supersoft X-ray sources: monitoring the evolution|
|Author||Dr Marina Orio|
|Description||We propose monitoring observations of supersoft X-ray sources. The classical nova V4743 Sgr, for which the best spectra of a luminous supersoft X-ray source have ever been obtained, should be monitored once again during the coming year, also in order to measure the length of hydrogen burning. We then propose that RX J0533.7-7034, a transient source observed for a few months in the LMC and never found to be luminous again, should be observed in five short snapshot exposures (every two and a half months) so that we may determine whether it underwent a hydrogen shell flash, and what its recurrence time scale may be.|

|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.
