Resumen:

Three exoplanets around the star HR 8799 have recently been discovered by differential imaging with large telescopes. In such cases, bright scattered starlight means that large angular offsets of the star are required for high-contrast imaging of the planets. Imaging at small angles requires a technique for reducing starlight and associated noise while still transmitting light from the planet. Here such a technique is described: all three HR 8799 planets have been detected using a vector vortex coronagraph on a small-aperture system
