Sources of X-ray emission in the high mass accretion rate nova-like UX UMa

UX UMa is the Xray brightest eclipsing novalike variable. This observation will enable us to compare the Xray behaviour of a system in a permanent highaccretion state with that of an SU UMa system in superoutburst. The superoutburst targets are not included here because of their need for TOO status. Manyof the scientific aims are common to the two proposals, but they are not.associated.. The questions to be addressed are: What is the source of Xrayemission in the high mass accretion rate regime Is the extended Xray source awind or static corona Can we solve the UV iron curtain conundrum. Can wedemonstrate for the first time that the secondary star is a significantcontributor to the Xray flux by detecting a secondary star eclipse truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
