An increasing amount of the literature reports the detection of magnetic fields in asymptotic giant branch (AGB) stars and in central stars of planetary nebulae (PNe). These detections lead to claims that the magnetic fields are the main agent shaping the PNe. In this paper, I examine the energy and angular momentum carried by magnetic fields expelled from AGB stars, as well as other physical phenomena that accompany the presence of large‐scale fields, such as those claimed in the literature. I… 
Weak magnetic fields in central stars of planetary nebulae
It is not yet clear whether magnetic fields play an essential role in shaping planetary nebulae (PNe), or whether stellar rotation alone and/or a close binary companion can account for the variety of
Magnetic fields in planetary nebulae and post-AGB nebulae
Magnetic fields are an important but largely unknown ingredient of planetary nebulae. They have been detected in oxygen-rich asymptotic giant branch (AGB) and post-AGB stars, and may play a role in
Magnetic fields in central stars of planetary nebulae
Most of the planetary nebulae (PN) have bipolar or other non-spherically symmetric shapes. The presence of a magnetic field in the central star may be the reason for this lack of symmetry, but
Common Envelope Shaping of Planetary Nebulae. II. Magnetic Solutions and Self-collimated Outflows
Magnetic fields of order 101–102 Gauss that are present in the envelopes of red giant stars are ejected in common envelope scenarios. These fields could be responsible for the launching of

Context. The origin of magnetism around asymptotic giant branch (AGB) stars remains an uncertainty. These stars may drive an important dynamo, but if the magnetic energy dissipates entirely into

Abstract Many, if not all, post AGB stellar systems swiftly transition from a spherical to a powerful aspherical pre-planetary nebula (pPNE) outflow phase before waning into a PNe. The pPNe outflows
Isolated versus common envelope dynamos in planetary nebula progenitors
The origin, evolution and role of magnetic fields in the production and shaping of protoplanetary nebulae (PPNe) and planetary nebulae (PNe) are a subject of active research. Most PNe and PPNe are
Search for surface magnetic fields in Mira stars: first results on χ Cyg
Abstract So far, surface magnetic fields have never been reported on Mira stars, while observational facilities allowing detection and measurement of weak surface fields through the Zeeman effect
Search for surface magnetic fields in Mira stars. First detection in χ Cygni
Context. So far, surface magnetic fields have never been detected on Mira stars. Only recently have the spectropolarimetric capabilities of measuring it via the Zeeman effect become available to us.
The Magnetic Field Effect on Planetary Nebulae
In our previous work on the 3-dimensional dynamical structure of planetary neb- ulae the effect of magnetic field was not considered. Recently Jordan et al. have directly de- tected magnetic fields


Dynamos in asymptotic-giant-branch stars as the origin of magnetic fields shaping planetary nebulae
It is shown that an asymptotic-giant-branch (AGB) star can indeed generate a strong magnetic field, having as its origin a dynamo at the interface between the rapidly rotating core and the more slowly rotating envelope of the star.
Local circumstellar magnetic fields around evolved stars
I argue that the presence of magnetic fields around evolved stars, e.g. asymptotic giant branch stars, and in planetary nebulae, does not necessarily imply that the magnetic field plays a global
Turbulent dynamo in asymptotic giant branch stars
Using recent results on the operation of turbulent dynamos, we show that a turbulent dynamo may amplify a large-scale magnetic field in the envelopes of asymptotic giant branch (AGB) stars. We
Magnetic Flares on Asymptotic Giant Branch Stars
We investigate the consequences of magnetic flares on the surface of asymptotic giant branch (AGB) and similar stars. In contrast to the solar wind, in the winds of AGB stars the gas cooling time is
Discovery of magnetic fields in central stars of planetary nebulae
For the first time we have directly detected magnetic fields in central stars of planetary nebulae by means of spectro- polarimetry with FORS1 at the VLT. In all four objects of our sample we found
Shaping Bipolar and Elliptical Planetary Nebulae: Effects of Stellar Rotation, Photoionization Heating, and Magnetic Fields
We present two-dimensional hydrodynamical and magnetohydrodynamical simulations of the evolution of planetary nebulae formed through the interaction of two succeeding, time-independent stellar winds.
Disk Formation by Asymptotic Giant Branch Winds in Dipole Magnetic Fields
We present a simple, robust mechanism by which an isolated star can produce an equatorial disk. The mechanism requires that the star have a simple dipole magnetic field on the surface and an
Magnetic shaping of planetary nebulae and other stellar wind bubbles
As in the case of the solar wind, the magnetic field in the wind from a magnetized, rotating star becomes increasingly toroidal with distance from the star. The strength of the magnetic field can be
The magnetic field around late-type stars revealed by the circumstellar H2O masers
Through polarization observations, circumstellar masers are excellent probes of the magnetic field in the envelopes of late-type stars. Whereas observations of the polarization of the SiO masers
On Circumstellar Envelope Formation
The origin of magnetic fields observed in circumstellar envelopes and proto-planetary nebulae is investigated theoretically. The build-up region of these fields is likely to be found deep in the
