When we count up the lithium atoms held in stars, there is only one-third as much of the lithium-7 isotope as there should be.

当我们算出了在各个恒星中锂原子的总数，同位素锂- 7的总量仅是在那里应有量的三分之一。

So if you engulf planet or large number of asteroids, you will have this Lithium-6 isotope in the spectrum of the star.

所以，如果恒星吞噬过行星，或大量的小行星，就会有锂—6同位素存在于恒星的光谱中。
