Characterizing geodesic deviations in a Topological Star spacetime: massive, charged, spinning and stringy-like objects

Abstract

We study deviations from geodesic motions in a Topological Star spacetime for either massive, charged and spinning particles, elucidating different behaviours with the Schwarzschild spacetime. We also consider the deviations for the motion of electrically charged stringy probes in $D=5$, framing all cases within a unified picture.
