Romano Corradi


Research interests:
Planetary nebulae: dynamics, morphology, microstructures, chemistry, distances, extragalactic PNe
Symbiotic stars : outflows
Spiral galaxies : ISM and dust

Recent highlights:
  1. Co-chair SOC: SYMBIOTIC STARS PROBING STELLAR EVOLUTION, 27-31 May 2002
  2. 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.

  3. 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.
