Wavefront tolerances of space-based segmented telescopes at very high contrast: Experimental validation
Iva Laginja, Jean-François Sauvage, Laurent M. Mugnier +8
Context: The detection and characterization of Earth-like exoplanets (exoEarths) from space requires exquisite wavefront stability at contrast levels of . On segmented te…
The mass of Beta Pictoris c from Beta Pictoris b orbital motion
S. Lacour, J. J. Wang, L. Rodet +96
We aim to demonstrate that the presence and mass of an exoplanet can now be effectively derived from the astrometry of another exoplanet. We combined previous astrometry of Pic…
Experimental validation of active control of low-order aberrations with a Zernike sensor through a Lyot coronagraph
Raphaël Pourcelot, Mamadou N'Diaye, Emiel H. Por +11
Future large segmented space telescopes and their coronagraphic instruments are expected to provide the resolution and sensitivity to observe Earth-like planets with a 10^10 contra…
Dark zone maintenance results for segmented aperture wavefront error drift in a high contrast space coronagraph
Susan F. Redmond, Laurent Pueyo, Leonid Pogorelyuk +8
Due to the limited number of photons, directly imaging planets requires long integration times with a coronagraphic instrument. The wavefront must be stable on the same time scale,…
Implementation of a broadband focal plane estimator for high-contrast dark zones
Susan F. Redmond, Laurent Pueyo, Leonid Pogorelyuk +6
The characterization of exoplanet atmospheres using direct imaging spectroscopy requires high-contrast over a wide wavelength range. We study a recently proposed focal plane wavefr…
LUVOIR-ECLIPS closed-loop adaptive optics performance and contrast predictions
Axel Potier, Garreth Ruane, Pin Chen +8
One of the primary science goals of the Large UV/Optical/Infrared Surveyor (LUVOIR) mission concept is to detect and characterize Earth-like exoplanets orbiting nearby stars with d…
