Accretion in a peculiar dwarf nova

We propose to observe EY Cyg, a dwarf nova that shows signatures of a past novaexplosion, an ideal target to study the physics of accretion. It is a knownXray source at low inclination, and a long period system, allowing a usefulcomparison with two short period novae recently observed in Xrays atquiescence, and with dwarf novae atlow inclination. EY Cyg is also one of veryfew relatively Xray bright cataclysmic variables at quiescence, but it hasnever been observed in Xrays except for very short, mostly serendipitousexposures. We have already studied this system in great detail at ultravioletand optical wavelengths, but good quality data in the Xray range are stillmissing. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
