Ultimately protoplanetary disks favor a transition phase involved in a supernova event rather than just the death of a star.

Completely incorrect and not even close to being the case.

Did you get permission from Davoud to comment or are you going to justify yourself like a cowed child the next time he chastises you ?. Men, how I wish there were adults who could discuss instead of trying to bite each other.

To be fair to you and everyone else, you would be required to state your alternative reasons as to how planetary systems form as the star travels around the galaxy along with all the other surrounding stars. Much easier to appreciate some supernova events as a transition phase which release the material for a solar system.

That conclusion was many years in development including the specific geometry of the rings which I had worked on before those images of the rings were taken back in May 1994.

I couldn't care less for those who cannot get into the stream of reasoning which links planetary formation with supernova events including our own Sun at one phase of its existence.
