Stars with exoplanets show distinct light element abundance patterns.
Significant trends in light element abundances are identified in these stars.
The review discusses implications for planet formation theories.
Abstract
It is well known that stars orbited by giant planets have higher abundances of heavy elements when compared with average field dwarfs. A number of studies have also addressed the possibility that light element abundances are different in these stars. In this paper we will review the present status of these studies. The most significant trends will be discussed.
