Description We propose to observe the peculiar Of?p star HD191612 for 3*20 ks with XMM-Newton. In the visible domain, this star displays spectacular line profile variations alternating between two different spectral states (O6-O8) with a period of ~540d. A monitoring of this peculiar object in the X-ray domain will provide crucial information for constraining its nature. The requested XMM data are part of a multiwavelength observing campaign that also includes coordinated observations in the UV (FUSE) and visible (ground-based telescopes) ranges.

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.
