Abstract

The formation of planetary nebulae is a poorly understood phase of stellar evolution. In particular it is still not clear what mechanism leads to the complicated morphologies observed in such sources. We have started a systematic study of objects in transition from post-AGB to planetary nebula, and in this poster we show some preliminary results.
