- Hydrodynamical modelling of the PN NGC2438 lead to the discovery of
`false' haloes in PNe, i.e. of ionised shells which are not the signature
of mass loss variations during the AGB phase of the progenitor. They are
instead the dynamical effect of the recombination front produced by a
sudden drop of the luminosity of the PN central star on its way to a white
dwarf.

- Recent HST images and ground-based spectra of the Southern Crab, the
ionised nebula around the symbiotic Mira He 2-104, reveal a new, puzzling
mass loss scenario from the systems, in which three different collimated
outflows are produced by the central source at approximately the same
epoch.
