IGR J17407-2808 is an enigmatic and poorly studied X-ray binary with variabilityproperties typical of the class of supergiant fast X-ray transients.Nevertheless, it hosts a late type-F dwarf star, which would classify it as alow-mass X-ray binary, although its X-ray properties are very different fromthose of this class. We propose a simultaneous NuSTAR and XMM-Newton observationto perform the most sensitive spectral and timing study of this source, on awide X-ray band (0.2-79 keV). The X-ray observations will be accompanied byoptical spectroscopic observations with X-sthooter and will enable us to collectinformation about IGR J17407-2808 fundamental to understand its nature and theX-ray emission mechanism that powers it.

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.
