I don't follow the connection with the Crab Nebula supernova. They claim that the supernova was this type III, but what about it leads to that claim? The article states it without support.
- rich_sasha 5y agoIt is believed Crab Nebula is the remnant of the 1054 supernova. We have detailed drawings of where in the sky it occured, and the Crab Nebula lies in a consistent location.
- mcphage 5y agoRight, I understand that, but what I don't understand is, what points to that supernova being a type III supernova?
- rich_sasha 5y agoHmm, haven’t read the article in enough detail, but again, the observations at the time, meticulously and redundantly kept, do not square up with what we see in the Crab Nebula. The original supernova light profile (eg how long it was visible in daylight for) doesn’t match what’s left for other known supernova types. Their light profiles are very specific to the type of explosion. This has been an open issue for a while.
- mcphage 5y agoGotcha, thanks :-)
