Analysis
This paper explores the theoretical possibility of 'ghost stars' within the framework of traversable wormholes. It investigates how these objects, characterized by arbitrarily small mass and negative energy density, might exist within wormhole geometries. The research highlights potential topological obstructions to their straightforward realization and provides a concrete example using a Casimir-like wormhole. The analysis of the Penrose-Carter diagram further illustrates the properties of the resulting geometry.
