| Description | The Supergiant Fast X-ray Transients (SFXTs) IGR J17354-3255 and SAX J1818.6-1703 are in the central region of the SFXT orbital period range and both show a high .recurrence. of periastron emission. Here we propose to perform sensitive, soft X-ray observations during the system periastron passages for the first time. These precisely targeted observations will maximise the probability of detecting pulsations in these systems and also allow us to place firm constraints on the stellar wind geometry within them. These measurements are essential to advance our current understanding of SFXTs, having the potential to alter the way in which we view the class as a whole and whether they can indeed be considered a single class of systems at all. |

| 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. |
