Diversity among other worlds: characterization of exoplanets by direct detection
J. Schneider, A. Boccaletti, A. Aylward +34
The physical characterization of exoplanets will require to take spectra at several orbital positions. For that purpose, a direct imaging capability is necessary. Direct imaging re…
Design, analysis and test of a microdots apodizer for the Apodized Pupil Lyot Coronagraph
P. Martinez, C. Dorrer, E. Aller Carpentier +4
Coronagraphic techniques are required to detect exoplanets with future Extremely Large Telescopes. One concept, the Apodized Pupil Lyot Coronagraph (APLC), is combining an apodizer…
Exoplanet characterization with long slit spectroscopy
Arthur Vigan, Maud Langlois, Claire Moutou +1
Extrasolar planets observation and characterization by high contrast imaging instruments is set to be a very important subject in observational astronomy. Dedicated instruments are…
End to End Simulation of AO-assisted coronagraphic differential imaging: estimation of performance for SPHERE
Anthony Boccaletti, Marcel Carbillet, Thierry Fusco +4
SPHERE (Spectro Polarimetric High contrast Exoplanet REsearch), the planet finder instrument for the VLT is designed to study relatively bright extrasolar giant planets around youn…
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…
Apodized Pupil Lyot Coronagraph Working Without Lyot Stop
Mamadou N'Diaye, Kjetil Dohlen, Salvador Cuevas
In the context of high contrast imaging, we propose to evaluate the performance of the Apodized Pupil Lyot Coronagraph (APLC) working without Lyot Stop, namely Stop-less Lyot Coron…
