First Images of R Aquarii and its Asymmetric HO Shell
S. Ragland, H. Le Coroller, E. Pluzhnik +7
We report imaging observations of the symbotic long-period Mira variable R Aquarii (R Aqr) at near-infrared and radio wavelengths. The near-infrared observations were made with the…
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…
Exoplanets imaging with a Phase-Induced Amplitude Apodization Coronagraph - I. Principle
Olivier Guyon, Eugene A. Pluzhnik, Raphael Galicher +3
Using 2 aspheric mirrors, it is possible to apodize a telescope beam without losing light or angular resolution: the output beam is produced by ``remapping'' the entrance beam to p…
