| Description | We propose to boost the current sample of flares observed with XMM-Newton from the confirmed Supergiant Fast X-ray Transients. Our recent milestone study of all observations available so far proved that a statistical analysis of these event can be exploited to demonstrate that these events are triggered by clumps in the supergiant wind and to probe the clumpy wind properties. However, the current number of flares is still small and more observations are needed. These flares occur randomly at any time with a recurrence time of few ks (2-5 flares expected every 20 ks observation, on average). The unique abilities of XMM needed for this study are the large effective area at soft X-rays and the possibility of having a uninterrupted lightcurves. |

| 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. |
