Abstract : Retrieving the mass distribution of exoplanets was performed for photometric observed planets from space-and ground-based surveys. True statistical distribution requires debiasing (correction) of observation selection. Retrieved distribution of transit exoplanets by mass accounts the probability of mass determination and the probability of transit configuration. As a not normalized probability density function (PDF), the corrected (debiased) exoplanet mass distribution can be approximated by the power law: dN/dm ∝ m-2. Minima significances in the retrieved mass distribution have been verified by Kolmogorov-Smirnov test.
