Cross-sectional slice in the binary orbital plane (XY) showing the density of Model A at various stages of the interaction between the nova ejecta and the accretion disk, subsequently followed by a collision with the main sequence companion. A movie showing the full evolution of this model, modelA-XY.avi, is available online. See also modelA-YZ.avi, for a movie depicting the evolution of the system from a side view (YZ plane). Snapshots and movies were generated by means of the visualization software SPLASH (Price 2007).
