Upgrading SPHERE with the second stage AO system SAXO+: non-common path aberrations estimation and correction
Johan Mazoyer, Charles Goulas, Fabrice Vidal +16
SAXO+ is a planned enhancement of the existing SAXO, the VLT/ SPHERE adaptive optics system, deployed on ESO's Very Large Telescope. This upgrade is designed to significantly enhan…
Characterisation of a turbulent module for the MITHIC high-contrast imaging testbed
A. Vigan, M. Postnikova, A. Caillat +6
Future high-contrast imagers on ground-based extremely large telescopes will have to deal with the segmentation of the primary mirrors. Residual phase errors coming from the phase…
First scattered-light images of the gas-rich debris disk around 49 Ceti
É. Choquet, J. Milli, Z. Wahhaj +31
We present the first scattered-light images of the debris disk around 49 ceti, a ~40 Myr A1 main sequence star at 59 pc, famous for hosting two massive dust belts as well as large…
Calibration of quasi-static aberrations in exoplanet direct-imaging instruments with a Zernike phase-mask sensor. II. Concept validation with ZELDA on VLT/SPHERE
M. N'Diaye, A. Vigan, K. Dohlen +14
Warm or massive gas giant planets, brown dwarfs, and debris disks around nearby stars are now routinely observed by dedicated high-contrast imaging instruments on large, ground-bas…
Laboratory validation of the dual-zone phase mask coronagraph in broadband light at the high-contrast imaging THD-testbed
J. R. Delorme, M. N'Diaye, R. Galicher +6
Specific high contrast imaging instruments are mandatory to characterize circumstellar disks and exoplanets around nearby stars. Coronagraphs are commonly used in these facilities…
