Scalar waves in a topological star spacetime: Self-force and radiative losses
Topological stars are solutions of Einstein-Maxwell theory in $D=5$. For specific choices of the parameters, the solution is capped and thus smooth and horizonless and can be reduced to $D=4$ along a circle. We study the energy and angular momentum radiated by a scalar particle moving on a circular orbit in the $D=4$ noncompact directions, extending a previous study [Phys. Rev. D 110, 084077 (2024)]. We also discuss self-force effects on the motion of a spinless probe.
