"Using the European Southern Observatory telescope in Atacama, Chile, the astronomers detected the presence of a rare variety of lithium in the star. The fragile metal would have been destroyed in the early, explosive evolutionary stages of this particular kind of star, which like our own is rich in heavy metals.
The best explanation that can account for the lithium is that the star ingested it much later, the Spanish and Swiss research team concluded."
Or maybe the star was psychotic, and needed to take lithium?
