Diversity among other worlds: characterization of exoplanets by direct detection
J. Schneider, A. Boccaletti, A. Aylward +34
The physical characterization of exoplanets will require to take spectra at several orbital positions. For that purpose, a direct imaging capability is necessary. Direct imaging re…
First Steps in Direct Imaging of Planetary Systems Like our Own: The Science Potential of 2-m Class Optical Space Telescopes
Karl Stapelfeldt, John Trauger, Weslay Traub +4
We summarize the scientific potential of high contrast optical space imaging for studies of extrasolar planets, debris disks, and planet formation. The unique scientific capabiliti…
Theoretical Limits on Extrasolar Terrestrial Planet Detection with Coronagraphs
O. Guyon, E. A. Pluzhnik, M. J. Kuchner +2
Many high contrast coronagraph designs have recently been proposed. In this paper, their suitability for direct imaging of extrasolar terrestrial planets is reviewed. We also devel…
Telescope to Observe Planetary Systems (TOPS): a high throughput 1.2-m visible telescope with a small inner working angle
Olivier Guyon, James R. P. Angel, Charles Bowers +20
The Telescope to Observe Planetary Systems (TOPS) is a proposed space mission to image in the visible (0.4-0.9 micron) planetary systems of nearby stars simultaneously in 16 spectr…
Exoplanet Imaging with a Phase-induced Amplitude Apodization Coronagraph III. Hybrid Approach: Optical Design and Diffraction Analysis
E. A. Pluzhnik, O. Guyon, S. T. Ridgway +4
Properly apodized pupils can deliver point spread functions (PSFs) free of Airy rings, and are suitable for high dynamical range imaging of extrasolar terrestrial planets (ETPs). T…
Limits of Adaptive Optics for high contrast imaging
Olivier Guyon
The effects of photon noise, aliasing, wavefront chromaticity and scintillation on the point spread function (PSF) contrast achievable with ground based adaptive optics (AO) are ev…
