Description We request to monitor 4 obscured HMXB composed by a neutron star and a supergiant OB companion (IGR J16320-4751, IGR J16393-4643, IGR J16418-4532, IGR J18027-2016 in order of preference) in order to study their spectral evolution along their orbital period, particularly the hydrogenic column density. We plan to observe IGR J16320-4751 8 times 5 ks and IGR J16393-4643, IGR J16418-4532 and IGR J18027-2016 5 times 7 ks for a total of 145 ks. Because of the strong interaction between the supergiant wind and the X-ray radiation of the accreted material, these sources are ideal laboratories to study the relation between the column density and the orbital period and derive the properties of the stellar wind.

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.
