The fastest-spinning white dwarf ever discovered is a shrinking cosmic vampire feasting on a stellar companion. A feeding process is pushing the dead star toward an imminent supernova explosion.

This leaves a smoldering stellar core, or white dwarf, surrounded by a spreading cloud of ex-stellar material. When the sun ...

This material stripped from the victim star is also believed to carry along angular momentum that further "spins up" the rotation of the feeding stellar vampires.

The re-emission of this material for 10 of the 24 black holes happened between two and six years after the star-destroying events. The observations are described in a study uploaded Aug. 25 to the ...
