Flight mask designs of the Roman Space Telescope Coronagraph Instrument
A J Eldorado Riggs, Dwight Moody, Jessica Gersh-Range +17
Over the past two decades, thousands of confirmed exoplanets have been detected; the next major challenge is to characterize these other worlds and their stellar systems. Much info…
Experimental analysis of the achromatic performance of a vector vortex coronagraph
Garreth Ruane, Eugene Serabyn, Camilo Mejia Prada +4
The vector vortex coronagraph is an instrument designed for direct detection and spectroscopy of exoplanets over a broad spectral range. Our team is working towards demonstrating c…
Microelectromechanical deformable mirror development for high-contrast imaging, part 1: miniaturized, flight-capable control electronics
Eduardo Bendek, Garreth Ruane, Camilo Mejia Prada +3
Deformable mirrors (DMs) are a critical technology to enable coronagraphic direct imaging of exoplanets with current and planned ground - and space-based telescopes as well as futu…
Wavefront sensing and control in space-based coronagraph instruments using Zernike's phase-contrast method
Garreth Ruane, J. Kent Wallace, John Steeves +14
Future space telescopes with coronagraph instruments will use a wavefront sensor (WFS) to measure and correct for phase errors and stabilize the stellar intensity in high-contrast…
Microelectromechanical deformable mirror development for high-contrast imaging, part 2: the impact of quantization errors on coronagraph image contrast
Garreth Ruane, Daniel Echeverri, Eduardo Bendek +8
Stellar coronagraphs rely on deformable mirrors (DMs) to correct wavefront errors and create high contrast images. Imperfect control of the DM limits the achievable contrast and, t…
The Habitable Exoplanet Observatory (HabEx) Mission Concept Study Final Report
B. Scott Gaudi, Sara Seager, Bertrand Mennesson +183
The Habitable Exoplanet Observatory, or HabEx, has been designed to be the Great Observatory of the 2030s. For the first time in human history, technologies have matured sufficient…
