A star/black hole pair near Earth reminds me of the set up if Greg Egan's Diaspora, a delightful far-future transhumanist hard sf novel people here would enjoy.
(Diaspora is a much more appealing story, at least for me, and probably my fave of his novels, but Incandescence does something unique: a discovery fiction of people figuring out elements of general relativity before newtonian mechanics.)
