Abstract

Statistical distributions of exoplanets obtained by both ground-based and satellite telescopes are heavily distorted by observational selection. It is easier to detect massive planets orbiting close to the star, rather than planets of small masses and planets with large orbital periods. Low-mass planets with orbital periods of about a year or more, falling in the habitable zone of sun-like stars, cannot be detected by modern means. To account for this factor, we proposed and investigated the method of correcting the observational selection. It has been shown that the corrected mass distributions of exoplanets are well described by a piecewise power law. The result is in agreement with the conclusions of cosmogony and demonstrates a number of new features.
