Calibration of residual aberrations in exoplanet imagers with large numbers of degrees of freedom
Raphaël Pourcelot, Arthur Vigan, Kjetil Dohlen +14
Imaging faint objects, such as exoplanets or disks, around nearby stars is extremely challenging because host star images are dominated by the telescope diffraction pattern. Using…

Direct characterization of young giant exoplanets at high spectral resolution by coupling SPHERE and CRIRES+
G. P. P. L. Otten, A. Vigan, E. Muslimov +19
Studies of atmospheres of directly imaged exoplanets with high-resolution spectrographs have shown that their characterization is predominantly limited by noise on the stellar halo…
