(This question was originally posted via World Building, but I was instructed to post it here) https://worldbuilding.stackexchange.com/questions/109457/is-a-supernova-powerful-to-destroy-the-other-star-in-a-binary-system?noredirect=1#comment332775_109457
The question is basically the same:
Can a binary star system have one of the two stars go supernova in the first place, and if so:
The first scenario would be:
- Star A of the binary swells to red giant status, and then is either touching or consumes star B: what would happen?
- Star A goes supernova, with maybe 1 AU of distance between it and Star B.
What info Id like to know:
- Can it destroy the other star via supernova?
- What is the effective range of the supernova, and can it destroy stars a light year or more away?
