Topological defects with axial symmetry: a disk+a string

The superimposed gravitational field of a string and a family of axisymmetric walls is analyzed. The resulting axisymmetric system is a topological defect. A striking observational feature is the appearance of a double-ring image from a distant point source. 26 refs.
