Description Supergiant Fast X-ray Transient are a sub-class of high mass X-ray binaries showing sporadic outbursts lasting only a few days, where most of the X-ray luminosity is concentrated in short (a few hours) X-ray flares reaching 1E36-1E37 erg-s. The driving mechanism is still highly debated, and involves models predicting magnetar-like neutron star magnetic fields (1E14 G) versus more typical values (1E12 G). IGRJ11215-5952 is the only SFXT with predictable outbursts, being periodic with a 165 day orbital period. This allows us to propose a XMM and NuSTAR joint observation (20 ks) to search for a cyclotron line and directly determine the NS magnetic field. This will enable to disentangle among the currently available models.

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.
