Supernova and Exoplanets: A Possible Connection?
(200 words excerpt, click title or image to see full post)

Last week, I posted about a recent supernova in our sky called the SN 2011fe in the Big Dipper. The title of that post does not imply any connection at all between supernovae and exoplanets other than the fact that there's a couple of known planet-bearing stars which can be exogazed in the same patch of sky roughly 7 degrees in diameter.

In this post however, i'm going out on a limb to investigate a possible relationship between exoplanets and supernovae that is more direct than simply being in the same patch of sky. I'm hoping that this post would serve as a prompt and a question for astrophysicists because i'm really curious if what i'm thinking is true or not.

Today, I read from an article that some old stars may be held held up by their rapid spins, like ticking time-bombs--the moment they slow down, they explode as supernovae. Immediately, I was reminded by an earlier finding that close-in exoplanets (commonly "Hot Jupiters") transfer angular momentum to their parent star which makes them spin faster.

Bringing these two research findings together, I therefore think that in some cases of these ticking "time-bombs on the verge of collapse", ...
