The imaging is spectacular but so must be the reasoning which allows solar systems to be born from their parent star hence certain supernova represent a transition phase rather than the death of a star -

The newer imaging shows the dust thrown up and rebounding against the smaller ring -

I have my own way of working with geometries but at no time am I willing to pander to exotic notions and physical impossibilities that defy logical progression as theorists are inclined to do.
Ultimately protoplanetary disks favor a transition phase involved in a supernova event rather than just the death of a star.
