I read more than one SF story based on the idea of life on suns.
It's an intriguing idea. Lord knows there's enough energy there to work with, but nobody has identified physics concepts (as yet) that would allow the organization and reproducibility of a life-type process.
Thinking along these lines leads to a lot of other speculation on life that might operate on totally different scales of size and time than ours does, and be a lot harder for us to identify as life.
