"Imagine
that the star originally formed rocky planets like Earth.
Furthermore, imagine that it also formed gas giant planets like
Jupiter," says Mack. "The rocky planets form in the region
close to the star where it is hot and the gas giants form in the
outer part of the planetary system where it is cold.
However, once
the gas giants are fully formed, they begin to migrate inward and, as
they do, their gravity begins to pull and tug on the inner rocky
planets. With the right amount of pulling and tugging, a gas giant
can easily force a rocky planet to plunge into the star. If enough
rocky planets fall into the star, they will stamp it with a
particular chemical signature that we can detect." Read more.
