Tidal Dwarf Galaxies: Their Present State and Future Evolution
  Evolutionary synthesis models for Tidal Dwarf Galaxies (TDGs) are presented that allow to have varying proportions of young stars formed in the merger-induced starburst and of stars from the merging spirals' disks. Comparing model grids with observational data (see e.g. P.-A. Duc this conference for a review) we try to identify the present evolutionary state of TDGs. The influence of their specific metallicities as well as of the gaseous emission of actively star forming TDGs on their luminosity and colour evolution are studied.
