Off the top of my head the Zinder nullifier is the only science fiction weapon I can think of that would do the job. Well that and Obie of course.....

Peter F. Hamilton's Commonwealth novels eventually see the development of "quantumbuster" weapons that can take out stars. The novels are all way too long but have good implementations of the Singularity (thus a millennia spanning epic that can have some continuous characters), wormhole travel, an actual alien intelligence and a Dyson sphere.
