Descripción
Extensive spectroscopic studies of stars with and without planetary systems
have concluded that planet host stars are more metal-rich than those without
detectable planets. More subtle trends of different chemical elements begin to
appear as the number of detected extrasolar planetary systems continues to
grow. I review our current knowledge concerning the observed abundance trends
of light and heavy elements in planet host stars and their possible
implications. These studies may help us to understand the chemical evolution
of our Galaxy at supersolar metallicities.
