We explore time-symmetric hypersurfaces containing apparent horizons of black objects in a 5D spacetime with one coordinate compactified on a circle. We find a phase transition within the family of such hypersurfaces: the horizon has different topology for different parameters. The topology varies from S3 to S2×S1. This phase transition is discontinuous—the topology of the horizon changes abruptly. We explore the behavior around the critical point and present a possible phase diagram.
