Data pubblicazione: | 2015 | Titolo del volume in cui è pubblicato il poster: | Adaptive Optics for Extremely Large Telescopes IV (AO4ELT4) | Da pagina:: | E11 | Abstract: | The SPHERE (Spectro-Polarimetric High-contrast Exoplanet Research) instrument aims at detecting extremely faint1sources (giant extrasolar planets) in the vicinity of bright stars . Such a challenging goal requires the use of a very-high-order performance Adaptive Optics [AO] system feeding the scientific instruments with a quasi-perfect flat wave front corrected from all the atmospheric turbulence and internal defects. This AO system, called SAXO (Sphere Ao for eXoplanet Observation) is the heart of the instrument, a heart beating 1200 time per second and providing unprecedented image quality for a large ground based telescope at optical/near infrared wavelength. We will present the latest results obtained on-sky, demonstrating its exceptional performance (in terms of correction quality, stability and robustness) and tremendous potentiality for exoplanet discovery. | Titolo del convegno: | Adaptive Optics for Extremely Large Telescopes 4 | Luogo del convegno: | Lake Arrowhead, California | Periodo del convegno: | October 25-30, 2015 | URI: | http://hdl.handle.net/20.500.12386/23959 | URL: | https://escholarship.org/uc/item/0gt3876k | DOI: | 10.20353/K3T4CP1131724 | Bibcode ADS: | 2015aoel.confE..11F | Fulltext: | open |
