in the giant planets of the system — since more metals means more solids in the feeding zone of the forming planet in its protoplanetary disk. However, Johanna Teske and collaborators have


conducted a detailed study of 22 exoplanet systems and show that this is not the case: there is no metallicity ‘enhancement’ for giant planets in metal-rich systems; the metal content of a


giant planet depends upon its mass. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Access Nature and 54 other Nature
