Rather than consider certain supernova as the death of a star, it may be considered a transition phase and the birth of a solar system.It is an area of research which extends to our own solar system

We share supernova events with people from antiquity such as the 1604 supernova event so its structure is an open discussion as much as its effects as opposed to just a theoretical entity. Long before images of SN1987a were taken, I had been working with a geometry using two large external rings and one smaller intersecting ring in 1990 so when I saw the images in May 1994 such a delight -

It is possible to treat the formation of a star as one thing and the birth of a solar system as something else and that approach is so appealing that I can't imagine what it must take not to pursue the structural components of stellar evolution including pre-supernova stars -
