"(though, there is not yet a potential candidate for a star in this range that died 359 million years ago)"

It might seem unlikely that such a candidate would be found 359 million years later. The solar system orbits the galaxy about once every 230 million years or so. The remnant of a supernova that might have caused such an event would not likely co-orbit with the sun after all this time.
