Amrutha Abstract Type : Poster Abstract Category : Stars, ISM and Galaxy Abstract : Around 25% of the central stars of Planetary Nebulae (PN) show Wolf-Rayat (WR) phenomena similar to massive stars. Though their precursors are AGB stars, the evolutionary path difference of [WR]PNe from those normal PNe is not known. The ionization structures of [WR]PNe will bring out the mass-loss history of these objects and in turn will help us to understand their evolutionary stage. We derive the ionization structures of a few PNe with [WR] and normal central stars from low resolution spectra obtained with VBT and using CLOUDY modelling. We discuss our preliminary results. We suggest that [WR]PNe are likely to have centrally condensed cores, unlike the normal PNe. |
