Description The coronal morphology of K- and M-dwarfs in pre-cataclysmic and cataclysmic binaries is important for their angular momentum loss and evolutionary paths to novae and Type 1a supernovae. Yet very little data on the coronae of such rapidly rotating stars exists. A 55ks observation of the recently identified X-ray-bright close (p=0.3d) K4V+M1V partially eclipsing binary DV Piscium presents an excellent opportunity to investigate coronal morphology at rotation rates similar to those of CV and pre-CV secondaries, and test directly whether coronally-saturated stars are dominated by polar coronae. The observation requires the large effective area of XMM-Newton.

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.
