Optical Breakthrough Could Detect Exoplanets Close to Host Stars

Astronomers from Leiden University and the University of Arizona have successfully commissioned a new type of optic that can reveal the image of an exoplanet next to its parent star.
The 'vector apodizing phase plate' (vector-APP) coronagraph was installed at the 6.5-m Magellan Clay telescope in Chile in May 2015, and the first observations demonstrated an unprecedented contrast performance very close to the star, where planets are more likely to reside. These results will be presented by PhD student Gilles Otten (Leiden) this Monday afternoon to the scientific community at the 'In the Spirit of Lyot'-conference held in Montreal
