Abstract

The common envelope interaction is responsible for evolved close binaries. Among them are a minority of central stars of planetary nebulae (PNe). Recent observational results, however, point to most PNe actually being in binary systems. We therefore ask the question if it is feasible that most, or even all Galactic PNe derive from a common envelope interaction. Our recent calculation finds that if all single and binary primary stars with mass between ∼1-8 M _⊙ eject a PN, there would be many more PNe in the Galaxy than observed. On the other hand, the predicted number of post-common envelope PNe is more in agreement with the total number of PNe in the Galaxy. This is a new indication that binary interactions play a functional role in the creation of PNe and an encouragement to intensify efforts to detect binary companions.
