If A Primordial Black Hole Hits The Sun...� - Technology Review: The likelihood is that a primordial black hole with mass of an asteroid or comet (about 10^21 g) would pass straight through the Sun, generating a small puff of X-rays in the process. Such a burst would be less even than the background rate of X-rays, so it would be impossible for astronomers to see.
Instead, Kesden and Hanasoge say that the collision would generate supersonic turbulence that would set the Sun ringing like a bell. Today, they calculate what these oscillations would look like.
