Abstract EN
The extrasolar planets in the vicinity of stars are expected to be bright enough and are very difficult to be observed by direct detection.
The problem is attributed to the side loops of the star that created due to the telescope diffraction processing.
Several methods have been suggested in the literatures are being capable to detect exoplanet at a separation angle of 4λ/D and at a contrast ratio of 10-10.
These methods are more than one parameter function and imposing limitations on the inner working distance.
New simple method based on a circular aperture combined with a third power Gaussian function is suggested.
The parameters of this function are then optimized based on obtaining a minimum inner working distance This method is capable of detecting exoplanet with an angular separation of 4λ/D and a contrast ratio of 10-10 and it is much easier to be implemented practically.
