Cold compact circumbinary rings evolve into highly eccentric disks with suppressed accretion and dominant variability at ~0.1 times the binary orbital frequency via a stream impact mechanism.
A nonlinear short-wavelength approximation for eccentric waves in discs yields conditions for steepening of nonlinearity and eccentricity, with solutions bounded by linear WKB results.
Semi-analytical theory derives radial scalings for forced disk eccentricity (E ~ r^{-1} or r^{-2}) and resonance criteria for precessing binaries, plus a conjecture that cavity size tunes the ground eccentric mode to the binary precession frequency.
GSC 08227-00723 is classified as a new AH Pic-type nova-like variable with recurrent stunted outbursts and an exceptionally large positive superhump excess of approximately 0.19.
