Query: Abundances in stars with exoplanets   Extensive spectroscopic studies of stars with and without planets have
concluded that stars hosting planets are significantly more metal-rich than
those without 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 various chemical elements in stars with exoplanets and their possible
implications.
