HCIPy is a package written in Python for simulating the interplay between wavefront control
and coronagraphic systems. By defining an element which merges values/coefficients with …

L'exoplanétologie est un domaine très actif de l'astronomie moderne avec des questions
encore ouvertes: comment les systèmes planétaires se forment-ils et évoluent-ils; pourquoi …

Context. Direct imaging of exoplanets takes advantage of state-of-the-art adaptive optics
(AO) systems, coronagraphy, and postprocessing techniques. Coronagraphs attenuate …

Micro-Electro-Mechanical Systems (MEMS) Deformable Mirrors (DMs) enable precise
wavefront control for optical systems. This technology can be used to meet the extreme …

The design of liquid-crystal diffractive phase plate coronagraphs for ground-based and
space-based high-contrast imaging systems is limited by the trade-off between spectral …

This paper introduces an analytical method to calculate segment-level wavefront error
(WFE) tolerances to enable the detection of faint extra-solar planets using segmented …

Because of bright starlight leakage in coronagraphic raw images, faint astrophysical objects
such as exoplanets can only be detected using powerful point spread function (PSF) …

Detection and characterization of Earth-like planets around nearby stars using the direct
imaging technique is a key scientific objective of future NASA astrophysics flagship …

One of the top priorities in observational astronomy is the direct imaging and
characterization of extrasolar planets (exoplanets) and planetary systems. Direct images of …

Context. One of the key noise sources that currently limits high-contrast imaging
observations for exoplanet detection is quasi-static speckles. Quasi-static speckles originate …
