High Angular Resolution and Extrasolar Planets: Beyond Basic Instrumental Performances
Abstract
Description
I review the characteristics of planetary systems accessible to imaging. I show that, beyond the basic angular resolution and dynamics performances of an optical ``architecture'', other performances such as photometric precision, spectral range or timing are necessary to access some physical characteristics of the planets.
