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

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. |
