SPHERE / ZIMPOL high resolution polarimetric imager. I. System overview, PSF parameters, coronagraphy, and polarimetry
H. M. Schmid, A. Bazzon, R. Roelfsema +59
We describe the Zurich Imaging Polarimeter (ZIMPOL), the visual focal plane subsystem of the SPHERE "VLT planet finder", which pushes the limits of current AO systems to shorter wa…
Photometric quality of Dome C for the winter 2008 from ASTEP South
Nicolas Crouzet, Tristan Guillot, Karim Agabi +13
ASTEP South is an Antarctic Search for Transiting Exo- Planets in the South pole field, from the Concordia station, Dome C, Antarctica. The instrument consists of a thermalized 10…
ASTEP South: An Antarctic Search for Transiting ExoPlanets around the celestial South pole
Nicolas Crouzet, Tristan Guillot, Karim Agabi +19
ASTEP South is the first phase of the ASTEP project (Antarctic Search for Transiting ExoPlanets). The instrument is a fixed 10 cm refractor with a 4kx4k CCD camera in a thermalized…
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…
