Abstract
The Terrestrial Planet Finder Coronagraph (TPF-C) is a future NASA mission to search for earth-like planets around nearby stars. Detecting a planet that is almost 10 billion times fainter than its parent star is extremely difficult, and it has been shown that polarization effects can cause stellar leakage which threatens that sensitivity goal. Building on our earlier work, we now show the combination of basic polarization effects with a representative coronagraph masking system, the eighth order linear field mask and Lyot stop, results in adequate performance.
