A long look at V1309 Ori: Towards an understand of the 'blobby' accretion proces
Abstract
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.
