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. |
