Scientific paper

It has been suggested (e.g., Madau, 1988) that there may exist a geometrically thick accretion torus at the center of active objects. This paper examines properties of a geometrically thick accretion torus, using photographs of an astrophysical torus taken by a distant observer, to calculate light curves during the primary eclipse of the torus in binary systems. The results were compared with observations of SS 433. The comparison indicated that the relativistic object in SS 433 is a black hole. This conclusion is consistent with the results of Antokhina and Cherepashchuk (1987), Stewart et al. (1987), and Kawai et al. (1989).
