Spectro-Polarimetric High-Contrast Exoplanet Research (original) (raw)
Spectro-Polarimetric High-contrast Exoplanet REsearch (VLT-SPHERE) is an adaptive optics system and coronagraphic facility at the Very Large Telescope (VLT). It provides direct imaging as well as spectroscopic and polarimetric characterization of exoplanet systems. The instrument operates in the visible and near infrared, achieving, albeit over a limited field of view, superior image quality and contrast for bright targets.

Spectro Polarimetric High contrast Exoplanet Research (SPHERE)L'instrument SPHERE attaché à son télescope, le VLT. SPHERE, de son nom complet Spectro Polarimetric High contrast Exoplanet REsearch (littéralement « Recherche d'exoplanètes par spectropolarimétrie à haut contraste »), en français Spectro-Polarimètre à Haut contraste destiné à la REcherche d'Exoplanètes, est un instrument de seconde génération installé sur le Très Grand Télescope de l'Observatoire européen austral, au Chili. L'objectif principal de SPHERE est l'imagerie directe de planètes extrasolaires. Cet instrument est composé d'un miroir déformable comprenant 1 300 actionneurs pouvant compenser 1 200 fois par seconde les perturbations dues aux turbulences de l'atmosphère terrestre.

It provides direct imaging as well as spectroscopic and polarimetric characterization of exoplanet systems. The instrument operates in the visible and near infrared, achieving, albeit over a limited field of view, superior image quality and contrast for bright targets. Results from SPHERE complement those from other planet finder projects which include HARPS, CoRoT, and the Kepler Mission. The instrument was installed on Unit Telescope "Melipal" (UT3) and achieved first light in June, 2014. At the time of installation, it was the latest of a series of second generation VLT-instruments such as X-shooter, KMOS and MUSE. (en) SPHERE (Spectro-Polarimetric High-contrast Exoplanet REsearch) è un sistema ottico spettrografico ad alto contrasto installato sull'unità 3 (UT3) del Very Large Telescope, presso l'osservatorio del Paranal, gestito dall'ESO. Lo strumento, dotato di ottica adattiva avanzata e coronografia, opera congiuntamente a tre sottosistemi ottimizzati per fornire un'alta qualità dell'immagine e prestazioni di contrasto in un campo visivo ristretto: * ZIMPOL (Zurich Imaging Polarimeter): un polarimetro che produce immagini vicine al valore di diffrazione limitante e immagini polarimetriche differenziali (DPI) con una risoluzione di 15 mas nello spettro visibile. * IFS: un'unita spettroscopica a campo integrale che produce un cubo di dati (datacube) di 38 immagini contemporanee monocromatiche. * IRDIS (infra-red dual imaging and spectrograph): un visualizzatore (imager) e spettrografo a doppia banda a infrarossi (it) |
