Spinning test body orbiting around a Kerr black hole: Comparing Spin Supplementary Conditions for Circular Equatorial Orbits

Understand

The worldline of a spinning test body moving in curved spacetime can be provided by the Mathisson-Papapetrou-Dixon (MPD) equations when its centroid, i.e.

• its center of mass, is fixed by a Spin Supplementary Condition (SSC).
• In the present study, we continue the exploration of shifts between different centroids started in a recently published work [ Phys.
