| Description | We propose XMM-Newton observations of the Compton-thick wind-fed Supergiant X-ray binary (SGXB) 4U 1909+07 (hereafter 4U1909) for 20(35) ks during the maximum (minimum) of its 15.2 day superorbital cycle. With the first XMM observation of the source we will test the physical mechanisms driving its 15.2 day modulation, in particular whether it is caused by Corotation Interaction Regions (hereafter, CIRs). By constraining the Fe fluorescence complex at different superorbital phases we will probe large-scale (high density and velocity) structures threading the wind of the B0-3 I donor star. Additionally, the large effective area and excellent timing resolution of EPIC will allow us to probe superorbital changes in the size and geometry of the circumstellar material by measuring changes in pul |

| 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. |
