Invited_talk abstract details

I shall review recent progress on understanding common-envelope evolution with emphasis on its end result, a (possibly bipolar) planetary nebula. Which stars will go into the common-envelope phase? How is it modelled? What is the outcome and will it lead to a planetary nebula? I will review both the detailed modelling approach, e.g. through hydrodynamical simulations, and the population/statistical comparison technique. Future prospects will be considered briefly, e.g. CE/PN research including calibration of models to observations through chemical yield comparisons and improved modelling of progenitors and lifetimes.
