Abstract | The coronal morphology of K- and M-dwarfs in pre-cataclysmic and cataclysmicbinaries is important for their angular momentum loss and evolutionary paths tonovae and Type 1a supernovae. Yet very little data on the coronae of suchrapidly rotating stars exists. A 55ks observation of the recently identifiedX-ray-bright close (p=0.3d) K4V+M1V partially eclipsing binary DV Pisciumpresents an excellent opportunity to investigate coronal morphology at rotationrates similar to those of CV and pre-CV secondaries, and test directly whethercoronally-saturated stars are dominated by polar coronae. The observationrequires the large effective area of XMM-Newton. |

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. |
