| Description | We propose a detailed spectroscopic study the SFXT IGR J18483-0311 at apastron, during its lowest X-ray luminosity state.To date this is the only SFXT which exhibits in its X-ray spectrum hints of two spectral emission lines at 3.28 keV and 5.04 keV. They have been ascribed to electron cyclotron emission and first harmonic respectively, allowing the first direct measurement of the NS magnetic field in a SFXT. We propose a 40 ks XMM observation aimed at obtaining: i) the firm detection of the two putative lines with good significance level,ii) the parameters of both lines with unprecedented accuracy iii) the location of the line-forming region. If firmly confirmed, this will be the first detection of a cyclotron feature in a SFXT, with crucial implications on the theoretical 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. |
