Description The eclipsing, long-period polar V1309 Ori is one of the most peculiar magnetic CVs. Most of its luminosity is radiated as flared soft X-rays, with no domintating contribution of a hot thermal plasma from the shock column above the white dwarf. Therefore V1309 Ori is the only clear-cut case of pure blobby accretion, where the impact mechanisms and radiation processs of a single accretion blob can be studied in detail. We propose one pointing of 60 ksec to cover two orbital cycles to collect data for around 300-600 flares.Primary aim is to derive a significant correlation between several important blob parameters like mass, temperature and length. Using this we will be able to discern between different impact mechanisms.

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.
