Talk:Seven Centre Stars/@comment-5135903-20131120184628

Apparently, in the centre of the Andromeda galaxy "Ten million solar masses are crowded into a volume less than 5 light-years in diameter." That would mean that each of the seven centre stars would have an average mass of about 1,428,571 solar masses! The most massive star we know of today is R136a1, at just 265 solar masses. I'm not sure if such large hypergiants would be feasible.
