Breaking degeneracies in exoplanetary parameters through self-consistent atmosphere-interior modelling
Christian Wilkinson, Benjamin Charnay, Stéphane Mazevet +5
Context: A new generation of instruments (e.g., JWST, ELTs, PLATO and Ariel) is providing atmospheric spectra and mass/radius measurements for large exoplanet populations, challeng…
Revisiting the Borde-Traub focal plane wavefront estimation technique for exoplanet direct imaging
Axel Potier, A J Eldorado Riggs, Garreth Ruane +8
Direct imaging of exoplanets relies on complex wavefront sensing and control architectures. In addition to fast adaptive optics systems, most of the future high-contrast imaging in…
A Deep Reinforcement Learning Approach to Wavefront Control for Exoplanet Imaging
Yann Gutierrez, Johan Mazoyer, Olivier Herscovici-Schiller +3
Exoplanet imaging uses coronagraphs to block out the bright light from a star, allowing astronomers to observe the much fainter light from planets orbiting the star. However, these…
Gemini Planet Imager Observations of a Resolved Low-Inclination Debris Disk Around HD 156623
Briley L. Lewis, Michael P. Fitzgerald, Thomas M. Esposito +12
The 16 Myr-old A0V star HD 156623 in the Scorpius--Centaurus association hosts a high-fractional-luminosity debris disk, recently resolved in scattered light for the first time by…
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…
Image-based wavefront correction using model-free Reinforcement Learning
Yann Gutierrez, Johan Mazoyer, Laurent M. Mugnier +2
Optical aberrations prevent telescopes from reaching their theoretical diffraction limit. Once estimated, these aberrations can be compensated for using deformable mirrors in a clo…
