Title Testing magnetic braking in close binaries

Author Dr Ralf Napiwotzki
Description We propose a systematic investigation of the stellar activity of M dwarfs in a sample of close binary systems with a white dwarf companion. We will use the X-ray flux as tracer of stellar activity and measure its dependence on the rotational periods. A comparison with results for single stars from the literature will assess whether both classes of M dwarfs follow the same relation. This will test whether the current concept of magnetic braking in close binaries is valid. Our results will have implications for many other types of close binary systems

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.
