|Title||What is the structure of NGC 1624-2.s giant magnetosphere?|
|Author||Dr Veronique Petit|
|Description||We propose to obtain new observations of the magnetic O star NGC 1624-2, which has the strongest magnetic field ever detected in a O-star. With such a strong field, NGC 1624-2 is trapping 95% of its wind into closed loops, and is a unique laboratory for the study of magnetically confined stellar winds. Two Chandra observations, obtained at rotational phases when the magnetic field is the closest to pole-on and equator-on, respectively, revealed that the intrinsic X-ray emission produced within the magnetosphere is strong, but heavily attenuated by the trapped wind. With the higher effective area of XMM-Newton, we will now use the variability of the X-ray flux and hardness over the stellar rotation to diagnose the hot plasma structure of NGC 1624-2.s enormous magnetosphere.|

|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.
