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…
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…
