Synthesis of Organic Compounds in Planetary Nebulae and Proto-Planetary Nebulae
AIP Conference Proceedings, 2006Recent millimeter‐wave and infrared spectroscopic observations have found evidence of rapid synthesis of complex organic molecules in the late stages of stellar evolution. The chemical synthesis begins with the formation of acetylene, the first building block of benzene, in carbon stars.

CO in Planetary Nebulae and Proto-Planetary Nebulae
1997The evolution between the asymptotic giant branch (AGB) and the planetary nebula (PN) phases has long been a “missing link” in our understanding of stellar evolution. Through the study of cool IRAS sources, an increasing number of transition objects, or “proto-planetary nebulae”, has now been identified.
