This analysis presents solutions mirroring black holes as compact stars, suggesting nonlinear electrodynamics and magnetic fields impact their properties.
We discuss a class of solutions of multidimensional gravity which are formally related to black-hole solutions but can observationally look like compact stars whose surface reflects back all particles or signals getting there. Some particular examples of such solutions are presented and studied, including those with a magnetic field in Maxwell or nonlinear electrodynamics (NED) in five dimensions. For NED as a possible source for magnetic mirror stars, we formulate a methodology of solving the 5D Einstein-NED equations and point out the conditions under which there always exist mirror star solutions. We also note that some of the Einstein-Maxwell solutions under consideration are discussed in the literature and called ``topological stars'' due to the circular topology of the fifth dimension.
