Abstract	The mass transfer and accretion mechanisms in SFXTs are key questions to placethem in the wider context of HMXB systems. Current theories centre on masstransfer via isotropic but inhomogeneous (a??clumpya??) winds, but some systemsalso show evidence of disk-like structures around the supergiant, analogous tothose seen in Be/X-ray binaries. We propose a campaign of periastronobservations of 2 SFXTs with known ephemerides. Simultaneous INTEGRAL/XMMobservations will measure the instantaneous accretion rate, emission spectrumand time variability generated on and around the neutron star. Continuousbroad-band observations around periastron yield the best opportunity to use theneutron star as a direct probe of the circumstellar wind environment.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
