|Title||XMM observation of W UMa type binaries|
|Author||Dr Fredericus Jansen|
|Description||GT- The W UMa systems are eclipsing binaries with components of spectral type F-K which are in contact via a common convective envelope. They have orbital periods shorter than a day and are strong X-ray emitters. Hence, W UMa binaries are of great interest in the study of the relation between stellar rotation rate and activity. The proposed observation will register RGS and EPIC spectra of 44 Boo and VW Cep during one full orbital period. The objective is to characterize the coronal structure of this W UMa systems using phase resolved spectroscopy.|

|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.
