Isaac Asimov has a novel with this exact premise, written in 1989, titled Nemesis (as if you expected something different). "Evil" companion star for the sun which caused all the mass extinctions, etc. Of course, in the novel there are multiple civilizations, a battle over whether Earth should be saved, etc... but the basic premise is the same.
17 years later, still just as fictional as it was then.
