| Abstract | We propose a systematic investigation of the stellar activity of M dwarfs in asample of close binary systems with a white dwarf companion. We will use theX-ray flux as tracer of stellar activity and measure its dependence on therotational periods. A comparison with results for single stars from theliterature will assess whether both classes of M dwarfs follow the samerelation. This will test whether the current concept of magnetic braking inclose binaries is valid. Our results will have implications for many other typesof close binary systems |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
