ISO Spectroscopy and Optical Morphology of Proto-planetary Nebulae and Young Planetary Nebulae
We present combined information on the optical morphology derived from HST images and the infrared properties of the dust in the circumstellar envelope derived from ISO SWS+LWS spectra for two proto-planetary nebulae (PPN) and two young planetary nebulae (PNe). The short phase from the AGB to the PNe stage is characterized by several episodes of
