| Popis: | Winds from accretion disks have been proposed as the driving source for precessing jets and extreme bipolar morphologies in Planetary Nebulae (PNe) and proto-PNe (pPNe). Here we apply MHD disk wind models to PNe and pPNe by estimating separately the asymptotic MHD wind velocities and mass loss rates. We discuss conditions which may occur in PNe and pPNe accretion disks that form via binary interactions. We show that the resulting winds can recover the observed momentum |
