Without magnetic forces our sun would be a hot but very boring object. There are so many papers on how MHD affects both PN shapes and SN remnant dispersion that one can get a bit addlepated trying to keep up with it all. Google Scholar lists the following references for MHD in PNs:

Very interesting comment, Dana. You are quite obviously someone who loves astrophysics.
I hope that I am going to have the time to read the papers you mention!
I have read some of Beck's papers on the magnetic fields within galaxies, and I have managed to understand some current ideas about the effects of magnetic fields in the formation of protostars and stars.
On the whole, I do look at things from the "galaxies" point of view:
I mainly read papers on the morphology and classification of galaxies, the kinematics/dynamics of galaxies and their constituents, on AGNs, plus the necessary papers on Star Formation and the ISM and Supernovae (for the purpose of enhancing my understanding of galaxies. )
I do wish that I knew more astrophysics so as to better interpret astronomical data, as I am more of the practical astronomer, with a love of good data and observations, such as: mass & luminosity functions of various objects, galaxy magnitudes, spectral line emission, photometric systems, distance measurement techniques, the space distribution & the peculiar velocity field of galaxies, etc.
However, as the career of Fritz Zwicky conclusively proved , you can discover an awful lot of things in astronomy without knowing every part of the physics; he had great physical insight, and an enormously creative ability to come up with new and physically plausible ideas, plus he was so extremely arrogant that he didn't at all care if everybody else thought that one of his ideas was very wrong. )
cheers, Robert
