Title: CK Vulpecula (nova 1670): The best test of the hibernation scenario
Abstract: Are classical novae, dwarf novae, novalike variables and (some) detached red dwarf-white dwarf binaries simply different phases of the same objects, and do they cycle back and forth between these states on timescales of millenia? This is the key prediction of the hibernation scenario of cataclysmic binary evolution. The nova of 1670 AD is the first, after the invention of the telescope, to have its position measured to within 1 arcmin, and its ejecta located. We have located a high proper motion red dwarf which was at the nebulosity center in 1670; it is a short period, radial velocity variable. We request 6 hours of Gemini-N GMOS longslit spectra to obtain time-resolved spectra of this red dwarf, to demonstrate that it must have a non-accreting white dwarf companion - and be the first-ever hibernating cataclysmic binary.
