A new method for reconstruction of silhouette of a transiting exoplanet is developed on the basis of derivative analysis of the transit light-curve (TLC). The method is able to detect the non-circular shapes of exoplanetary shadows, although sometimes the reconstructed non-spherical silhouettes are distorted. The proposed method shows the presence of a ring or disk for the planet KOI 1729.01, whereas other similarly studied objects (13 from 18) have quasi-circular shadows.
