Unless you blew up the sun with sufficient energy to completely disperse it in space,
I think it would rapidly reform, because there's still a whole stellar mass in roughly the same space at the same time, blowing it up is just making it a lot less dense, briefly. Its centre of mass would still be in the same place...

It would be pretty angry for the next few billion years or so but subterranean microbes would probably survive and life would begin again.
