SPHERE+: Imaging young Jupiters down to the snowline
A. Boccaletti, G. Chauvin, D. Mouillet +130
SPHERE (Beuzit et al,. 2019) has now been in operation at the VLT for more than 5 years, demonstrating a high level of performance. SPHERE has produced outstanding results using a…
High-contrast imager for Complex Aperture Telescopes (HiCAT): 3. first lab results with wavefront control
Mamadou N'Diaye, Johan Mazoyer, Elodie Choquet +9
HiCAT is a high-contrast imaging testbed designed to provide complete solutions in wavefront sensing, control and starlight suppression with complex aperture telescopes. The pupil…
Calibration of quasi-static aberrations in exoplanet direct-imaging instruments with a Zernike phase-mask sensor. III. On-sky validation in VLT/SPHERE
A. Vigan, M. N'Diaye, K. Dohlen +12
Second-generation exoplanet imagers using extreme adaptive optics and coronagraphy have demonstrated their great potential for studying close circumstellar environments and for det…
Apodized Pupil Lyot Coronagraphs with arbitrary aperture telescopes: novel designs using hybrid focal plane masks
Mamadou N'Diaye, Kevin Fogarty, Rémi Soummer +6
Exoplanet imaging and spectroscopy are now routinely achieved by dedicated instruments on large ground-based observatories (e.g. Gemini/GPI, VLT/SPHERE, or Subaru/SCExAO). In addit…
Experimental test of a 40 cm-long R=100 000 spectrometer for exoplanet characterisation
Guillaume Bourdarot, Etienne Le Coarer, David Mouillet +12
High-resolution spectroscopy is a key element for present and future astronomical instrumentation. In particular, coupled to high contrast imagers and coronagraphs, high spectral r…
Active correction of aperture discontinuities (ACAD) for space telescope pupils: a parametic analysis
Johan Mazoyer, Laurent Pueyo, Colin Norman +6
As the performance of coronagraphs improves, the achievable contrast is more and more dependent of the shape of the pupil. The future generation of space and ground based coronagra…
