Abstract
The paper investigates a wormhole model obtained by combining the Bardeen space-time of mass and charge on the one side and the Schwarzschild space-time of mass on the other. These objects are spherically symmetric in shape, but not reflectively symmetric, since the associated space-times are different. Reflectively asymmetric wormholes can reflect a significant portion of the incident radiation back into the spacetime in which it originated. Previously, this effect was considered in terms of the effective photon potential. Depending on the parameters of the model, the image of such a wormhole seen by a distant observer (its "shadow") may contain a photon ring formed on the side of the observer and a photon ring formed on the other side of the wormhole, or both photon rings. These unique topological features will allow us to clearly distinguish this class of objects from black holes using radio astronomy observations.
