Dust in nova system - thoughts in transition

The evidence for the presence of dust around cataclysmic variables is reviewed with particular emphasis on classical novae. Two general models - rapid grain formation and pre-existing grains - for infrared development of novae are critically discussed and relevant observations of other cataclysmic variables that have some bearing on these models are described. It may be premature to opt for either model at this stage and further observations which may provide more evidence are suggested. An understanding of dust formation in cataclysmics - by whatever mechanism - could provide valuable information about several important astrophysical processes. (author)
