|Title||EPIC Observations of the X-ray and Radio Source LS I +61d303 - GT 0236+610|
|Author||Dr Martin Turner|
|Description||GT- GT0236+610 is an X-ray-radio- (and possibly gamma-ray) source with unique properties, associated to the Be star LSI+61 303 and characterized by strong non thermal outbursts occurring with a periodicity of 26.5 days. The proposed observation with 4 snapshots at different orbital phases will allow to discriminate between the two alternative models of shock emission and supercritical accretion. NOTE FOR THE PLANNING: 4 pointings of 5 ksec each are required, in order to cover different phases of the 26.5 day orbit. The choice in the time constraints form (repeat every 3 orbits) is just a possibility: such a tight constraint on the spacing is not required, as far as different phases are sampled.|

|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.
