What Happens to a Star That Captures A Primordial Black Hole?

This illustration shows a primordial black hole (PBH) inside a Sun-like star. New simulations show that if a star captured a PBH, there are two potential outcomes. One sees the star destroyed rapidly, the other sees the PBH gradually consume the star. Image Credit: MPA, background image: Wikimedia/Creative Commons.

Stephen Hawking predicted that stars can capture primordial black holes (PBH). The PBH find their way to the stellar core, creating a Hawking star. There are two possible outcomes, both deadly for the star. Either it explodes rapidly, or it's slowly consumed by the parasitic PBH.
