抄録

We have calculated theoretical light curves of SS 433 during precession, using a model in which SS 433 consists of a geometrically thick torus around a compact star and a companion star filling the Roche lobe. Inorder to interpret a bright hump at the precession phase of 0 (the torus is seen from the "bottomside"), the configuration of the torus is not very thick, but should be rather thin (at least mildly thin). Combinations of light curves during eclipse and precession impose several constraints on the physical parameters: the binarymass ratio, torus configuration, and surface temperature of the companion. The favorite combination is a mass ratio of about 2 (a compact star is a black hole) and a surface temperature of the companion of around 17000 K.
