A debris disk spied recently around a distant dead star is likely the remains of an asteroid that was vaporized when the star died, scientists say.
The discovery, detailed in the Dec. 22 issue of the journal Science, could be a sign of what will happen in our own solar system in a few billion years. Because the crushed asteroid was probably gravitationally lassoed in by one or more planets, the finding also provides evidence that planetary systems can form around massive stars. . ."
