The Takeaway
Unlike normal stars that shine or black holes that swallow light, these theoretical objects would perfectly reflect everything that hits them. They represent a new class of stable cosmic structures that would be completely invisible unless something illuminated them from the outside.
From the abstract
We consider static, spherically symmetric solutions of 5D general relativity with magnetic fields governed by nonlinear electrodynamics (NED) with the Lagrangian $L(F)$, $F = F_{AB} F^{AB}$, and show that generic solutions describe either 5D black holes (also called black strings due to a circular extra dimension) or so-called mirror stars (also called topological stars) with perfectly reflecting boundary surfaces. Two particular examples of such solutions have been obtained, admitting analytic
