| Abstract | We propose to observe two intermediate polars - AO Psc and FO Aqr - which aretypical of their class, well studied, and which are among the X-ray brightestin the class. By comparing the two stars we will begin to understand why someIPs have broad iron lines and others narrow lines; why some have simple pulseprofiles and others complex profiles; why some have soft components andothers not, etc. We will make simultaneous observations of the hard-X-rayemitting accretion shock, the heated accretion polecap, the absorption in theshock and the accretion flow, and the optical/UV-emitting transition regionbetween the disc and the magnetic field. The temperatures, densities, |

| 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. |
