Overview of focal plane wavefront sensors to correct for the Low Wind Effect on SUBARU/SCExAO
Sebastien Vievard, Steven Bos, Frederic Cassaing +15
The Low Wind Effect (LWE) refers to a phenomenon that occurs when the wind speed inside a telescope dome drops below m/s creating a temperature gradient near the telescope spide…
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…
Kernel-phase Detection Limits : Hypothesis Testing and the Example of JWST NIRISS Full Pupil Images
Alban Ceau, David Mary, Alexandra Greenbaum +4
The James Webb Space Telescope will offer high-angular resolution observing capability in the near-infrared with masking interferometry on NIRISS, and coronagraphic imaging on NIRC…
ESA Voyage 2050 White Paper: Detecting life outside our solar system with a large high-contrast-imaging mission
Ignas Snellen, Simon Albrecht, Guillem Anglada-Escude +64
In this white paper, we recommend the European Space Agency plays a proactive role in developing a global collaborative effort to construct a large high-contrast imaging space tele…
An Exo-Kuiper Belt and An Extended Halo around HD 191089 in Scattered Light
Bin Ren, Élodie Choquet, Marshall D. Perrin +70
We have obtained Hubble Space Telescope STIS and NICMOS, and Gemini/GPI scattered light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling K…
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…
High-Contrast Testbeds for Future Space-Based Direct Imaging Exoplanet Missions
Johan Mazoyer, Pierre Baudoz, Ruslan Belikov +25
Instrumentation techniques in the field of direct imaging of exoplanets have greatly advanced over the last two decades. Two of the four NASA-commissioned large concept studies inv…
Apodized pupil Lyot coronagraphs designs for future segmented space telescopes
Kathryn St. Laurent, Kevin Fogarty, Neil T. Zimmerman +8
A coronagraphic starlight suppression system situated on a future flagship space observatory offers a promising avenue to image Earth-like exoplanets and search for biomarkers in t…
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…
High-contrast imager for complex aperture telescopes (HiCAT): 5. first results with segmented-aperture coronagraph and wavefront control
Remi Soummer, Gregory R. Brady, Keira Brooks +19
Segmented telescopes are a possibility to enable large-aperture space telescopes for the direct imaging and spectroscopy of habitable worlds. However, the complexity of their apert…
