With over 100 extrasolar planets now known, a striking trend has been found in the above-average metallicities of their parent stars. This pattern may be due to the accretion of metal-rich material from infalling planets. Based on a stellar evolution code developed to model stars with elevated convection zone metallicity, I will discuss the primary effects that metal pollution is expected to have on stellar structure and evolution. I will also present several applications to this work, including (1) analysis of binary systems whose components have differing iron abundances and (2) calculations of p-mode oscillation frequencies in polluted solar-type stars.
