|Title||The X-ray Variability of HD 5980, the SMC.s "Eta Carinae"|
|Author||Dr Michael Corcoran|
|Description||HD 5980 is an Eta Car-like binary system in which one of the stellar components is an eruptive Luminous Blue Variable. Unlike Eta Car, the nature of the X-ray variability of HD 5980 is unclear. We propose to re-observe HD 5980 with XMM to measure the X-ray brightness at four critical orbital phases to constrain the phase dependence of the X-ray emission and to provide a benchmark for future spectrographic observations with XMM and CHANDRA. The observations we propose, combined with previous CHANDRA and XMM observations, will determine the importance of colliding wind X-ray emission from this system and will also help constrain how the X-ray emission depends on the variable mass loss from the LBV component.|

|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.
