| Description | GT-We propose to perform XMM observations of bright eclipsing polars in order to solve several open questions of magnetic accretion: What are the sizes of X-ray emitting hot spots on the white dwarfs? Is there X-ray emission from the accretion stream and the secondary star (spectral type typically M5V)? What is the influence of the magnetic field on the cooling plasma? The proposed observations will make full use of the combined optical/X-ray telescope assembly onboard XMM, since all major emitters can be observed in one observation: soft and hard X-ray emission from the hot spot, cyclotron radiation from the spot and recombination radiation from the stream in the optical. |

| 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. |
