Model Predictions of the Results of Interferometric Observations for   Stars under Conditions of Strong Gravitational Scattering by Black Holes and   Wormholes
  The characteristic and distinctive features of the visibility amplitude of interferometric observations for compact objects like stars in the immediate vicinity of the central black hole in our Galaxy are considered. These features are associated with the specifics of strong gravitational scattering of point sources by black holes, wormholes, or black_white holes. The revealed features will help to determine the most important topological characteristics of the central object in our Galaxy: whether this object possesses the properties of only a black hole or also has characteristics unique to wormholes or black_white holes. These studies can be used to interpret the results of optical, infrared, and radio interferometric observations.
