Abstract: Central stars of extra-solar planetary systems are metal-rich. Planet accretion or initial surmetallicity can explain this observational fact. These scenarios can be tested with asteroseismology. We calibrate two stellar models, one with accretion and one with high initial metallicity, in order to obtain the same external parameters for both of them. We then compare their internal structures and their oscillation frequencies.
