Only supermassive stars go supernova; stars like our Sun will eventually go nova, which is non-explosive (though it'll expand to bigger than the orbit of the Earth, uh-oh). They're too massive to move, as well.
However, they might get their atmospheres torn off, and the gas and dus around them will almost certainly get blown into deep space. So they're as big as they're going to get.
