The Evolution of Nova Remnants

In this review I concentrate on describing the physical characteristics and evolution of the nebular remnants of classical novae. I also refer as appropriate to the relationship between the central binary and the ejected nebula, particularly in terms of remnant shaping. Evidence for remnant structure in the spectra of unresolved novae is reviewed before moving on to discuss resolved remnants in the radio and optical domains. As cited in the published literature, a total of 5 remnants have now been resolved in the radio and 44 in the optical. This represents a significant increase since the time of the last conference. We have also made great strides in understanding the relationship of remnant shape to the evolution of the outburst and the properties of the central binary. The results of various models are presented. Finally, I briefly describe new results relating to the idiosyncratic remnant of GK Per (1901) which help to explain the apparently unique nature of the evolving ejecta before concluding with a discussion of outstanding problems and prospects for future work.
