Description Supergiant Fast X-ray Transients (SFXT) are very variable high mass X-ray
binaries in our galaxy. Two models have been proposed to interpret their
behavior: (i)a gating mechanism, involving either the centrifugal barrier or
ultramagnetic neutron stars (magnetars); (ii)an extermely clumpy wind from the
supergiant companion. Here we propose to study the quiescent emission of three
SFXTs. By making a comparison between their quiescence and outburst spectra and
searching for pulsations and column density variations, we will test the
applicability of the above models. These sources might well provide the very
first opportunity to detect and study magnetars in binary systems. In any case,
very crucial information will be obtained to test the prediction of modern theories of radiatively-driven winds.

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.
