Contribution

It provides a comprehensive analysis of geodesic deviations for different particles in Topological Star spacetimes, including charged, spinning, and stringy probes, within a unified framework.

Findings

Distinct deviation behaviors compared to Schwarzschild spacetime

Unified description for massive, charged, spinning, and stringy probes

Insights into higher-dimensional stringy effects on geodesics

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.
