Improving VLT/SPHERE without additional hardware: Comparing quasi-static correction strategies
Axel Potier, Zahed Wahhaj, Raphael Galicher +4
Direct imaging is the primary technique currently used to detect young and warm exoplanets and understand their formation scenarios. The extreme flux ratio between an exoplanet and…
Random Vibration Testing of Microelectromechanical Deformable Mirrors for Space-based High-Contrast Imaging
Axel Potier, Camilo Mejia Prada, Garreth Ruane +11
Space-based stellar coronagraph instruments aim to directly image exoplanets that are a fraction of an arcsecond separation and ten billion times fainter than their host star. To a…
Increasing the raw contrast of VLT/SPHERE with the dark-hole technique. II. On-sky wavefront correction and coherent differential imaging
Axel Potier, Johan Mazoyer, Zahed Wahhaj +4
Context. Direct imaging of exoplanets takes advantage of state-of-the-art adaptive optics (AO) systems, coronagraphy, and post-processing techniques. Coronagraphs attenuate starlig…
Contrast performance of an 8m off-axis, segmented space telescope equipped with an adaptive optics system
Axel Potier, Garreth Ruane, Kiarash Tajdaran +9
The Astro2020 decadal survey recommended an infrared, optical, ultra-violet (IR/O/UV) telescope with a 6~m inscribed diameter and equipped with a coronagraph instrument to di…
