Eyes in the sky: Interactions between asymptotic giant branch star winds and the interstellar magnetic field
This is the most comprehensive study to date of the effects of weak magnetic fields on the expansion of evolved star winds. While the basic result is to be expected — that the interstellar magnetic field produces distinctly elongated, aspherical structures — the details are important for issues such as turbulence, shock structures, and transport of stellar nuclear products (hence mixing in the interstellar medium). The models are compared to Herschel images of wind-blown bubbles, but this will also be important for future missions, such as JWST, as well as for polarization studies.
