|Title||High Resolution Spectroscopy of Cen X-3 in Eclipse|
|Author||Dr Albert Brinkman|
|Description||GT- We propose an observation of Cen X-3 over an eclipse and a portion of the out-of-eclipse interval. The Cen X-3 system contains diffuse gas in an extended stellar wind as well as dense gas in a small region near the neutron star. The X-rays which are reprocessed in the circumstellar gas carry spectral signatures which are diagnostic of the density and temperature of that gas. During eclipse, the reprocessed radiation from the extended wind can be observed without the much more intense direct radiation from the neutron star. While the neutron star is out of eclipse, the X-rays reprocessed in the dense gas near the neutron star can be observed. We propose to use some instruments in timing mode in order to observe the pulsations in the iron fluoresence line.|

|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.
