Computer simulations of direct imaging of extrasolar planets

الملخص EN

Numerical simulations are carried out to investigate the possibility of observing extrasolar planet nearby star via optical telescopes.

Several techniques are considered in this study in order to quantitatively assess their quality in suppressing the wings of the point spread function of optical telescope of a reference star.

The optical telescope with circular Gaussian shape aperture reveals extrasolar planet even with contrast ratio 10-7 while the square Gaussian shape aperture reveals the planet with 10-5.
