Abstract
Using the results of recent work in shear instabilities in stratified fluid s, we show that the resonant interaction between large-scale flows in the a ccreted H/He envelope of white dwarf stars and interfacial gravity waves ca n mix the star's envelope with the white dwarf's surface material, leading to the enhancement of the envelope's C/O abundance to levels required by ex tant models for nova outbursts.
