The SPHERE infrared survey for exoplanets (SHINE) V. Full sample characterization

V. Squicciarini, S. Desidera, G. Chauvin +109

Unbiased surveys of large stellar samples are the prime means through which the prevalence of exoplanets can be derived, and crucial constraints to planet formation models can be s…

First light of VLT/HiRISE: High-resolution spectroscopy of young giant exoplanets

A. Vigan, M. El Morsy, M. Lopez +46

A major endeavor of this decade is the direct characterization of young giant exoplanets at high spectral resolution to determine the composition of their atmosphere and infer thei…

Validation of strategies for coupling exoplanet PSFs into single-mode fibres for high-dispersion coronagraphy

M. El Morsy, A. Vigan, M. Lopez +13

On large ground-based telescopes, the combination of extreme adaptive optics (ExAO) and coronagraphy with high-dispersion spectroscopy (HDS), sometimes referred to as high-dispersi…

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…
