RESUMO
We describe a high-contrast imaging technique capable of directly measuring light from a terrestrial planet by using a vortex mask of topological charge m = 5. We demonstrate that this technique is relatively insensitive to low-order aberrations and compare its performance to that of a band-limited Lyot coronagraph.
