Does the shape of a supernova remnant depend on the progenitor star's magnetic field? The magnetic field activity in a star can be very chaotic and my question is are they somehow related?
The factors that affect the shape of supernova remnants include:


Interstellar medium (the gas and particles between stars)
Planets that surrounded the star
Magnetic field (in the same way magnetic fields cause auroras)
Mass distribution of the star before supernova


There are probably more, but that's all I can think of at the moment
