This study of protoplanetary systems affirms the anthropic principle. Astronomers have discovered that planet-eating stars are more common in the universe than they thought and, consequently, Earth’s solar system is more special than they thought. In a forming planetary system planets accrete, or pull in, the outer disk (dust cloud) while the central star accretes the inner disk. If the planets fail to accrete the outer disk before the star accretes the inner disk, they will migrate or drift right into the star. This result explains the existence of very metal-rich stars (they “polluted” themselves with their own planets) and helps explain why planetary systems capable of harboring a life-supportable planet have yet to be discovered outside of the solar system.
