I review some open questions and other aspects concerning the shaping of planetary nebulae (PNs) and related objects. I attribute the non-spherical structures of PNs to binary companions, stellar or substellar. I emphasize the role of jets (or collimated fast wind: CFW) blown by an accreting stellar companion in shaping PNs and some related objects, and discuss the limited role of magnetic fields. I speculate that some stars which are leaving the asymptotic giant branch, i.e., becoming hotter…

The roughly spherical outer regions and aspherical inner regions of protoplanetary nebulae — here imaged by ALMA — are explained in terms of an embedded binary system with stars on eccentric orbits.

AGBs, Post-AGBs and the Shaping of Planetary Nebulae

During the last decades, observations, mostly with the Hubble Space Telescope, have revealed that round Planetary Nebulae were the exception rather than rule. A huge variety of features are observed,
