Abstract

Two-dimensional computer simulations are carried out to demonstrate the
essential features of observing extrasolar planet nearby star. It has been shown that
the wings of the point spread function of the optical telescope play an important rule
in suppressing the features that related to the planet. The planet lies beneath these
wings and the final image that recorded by an optical telescope looks like a star.
Quantitative assessment of observing planet nearby star at different relative
brightness and separation are demonstrated in this study.
