High-order myopic coronagraphic phase diversity (COFFEE) for wave-front control in high-contrast imaging systems
B. Paul, L. M. Mugnier, J. -F. Sauvage +1
The estimation and compensation of quasi-static aberrations is mandatory to reach the ultimate performance of high-contrast imaging systems. COFFEE is a focal plane wave-front sens…
Performances tests on the SPHERE-IFS
Dino Mesa, Raffaele Gratton, Riccardo U. Claudi +13
Until now, just a few extrasolar planets (~30 out of 860) have been found through the direct imaging method. This number should greatly improve when the next generation of High Con…
Calibration of quasi-static aberrations in exoplanet direct-imaging instruments with a Zernike phase-mask sensor
M. N'Diaye, K. Dohlen, T. Fusco +1
Context. Several exoplanet direct imaging instruments will soon be in operation. They use an extreme adaptive optics (XAO) system to correct the atmospheric turbulence and provide…
Apodization in high-contrast long-slit spectroscopy. Closer, deeper, fainter, cooler
A. Vigan, M. N'Diaye, K. Dohlen
The spectroscopy of faint planetary-mass companions to nearby stars is one of the main challenges that new-generation high-contrast spectro-imagers are going to face. In a previous…
Speckle temporal stability in XAO coronagraphic images II. Refine model for quasi-static speckle temporal evolution for VLT/SPHERE
P. Martinez, M. Kasper, A. Costille +4
Observing sequences have shown that the major noise source limitation in high-contrast imaging is due to the presence of quasi-static speckles. The timescale on which quasi-static…
