| Abstract | We propose to obtain the first deep observations in the UV (currently constrained only with the XMM-Newton OM), with high cadence HST FUV imaging of aQPE with eruptions lasting only 27 min and recurring every 114 min. Thesetimescales are perfectly suited to perform the first time-resolved UVvariability search during the X-ray eruptions. With HST sensitivity in the FUVthis will lead to a >2 orders of magnitude improvement compared to currentconstraints. A detection of UV variability and how it correlates with the X-rayswill have field-defining implications that will redraw the theoreticallandscape. Non-detections will provide very strong additional constraints on thegeometry, extent and properties of the putative accretion disks |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
