Jet Formation in the Transition from the Asymptotic Giant Branch to Planetary Nebulae
Abstract
The possibility is studied that during its transition from the AGB to the central star of a PN, a rotating star blows a collimated wind along the symmetry axis. The wind results from the deformation of the stellar surface due to fast rotation. Evolutionary calculations using a spherical stellar model are used to argue that an essential ingredient in the proposed scenario is that the evolving star is in a common envelope with a lower mass companion which spins up the envelope.
