First light from the Dome C (Antarctica) of a phase knife stellar coronagraph
Geraldine Guerri, Lyu Abe, Jean-Baptiste Daban +4
We report on the first daytime on-sky results of a Phase Knife stellar Coronagraph operated in the visible from the French-Italian Concordia station at Dome C of Antarctica. This s…
Apodized Lyot Coronagraph for VLT-SPHERE: Laboratory tests and performances of a first prototype in the visible
Géraldine Guerri, Sylvie Robbe-Dubois, Jean-Baptiste Daban +9
We present some of the High Dynamic Range Imaging activities developed around the coronagraphic test-bench of the Laboratoire A. H. Fizeau (Nice). They concern research and develop…
Prototyping coronagraphs for exoplanet characterization with SPHERE
Anthony Boccaletti, Lyu Abe, Jacques Baudrand +7
The detection and characterization of extrasolar planets with SPHERE (Spectro Polarimetric High contrast Exoplanet REsearch) is challenging and in particular relies on the ability…
The close-in companion of the fast rotating Be star Achernar
