Separability of the motion of spinning test particles in curved space-time
VojtÄch Witzany, Viktor Skoupý
Solving for the motion of spinning test particles in curved spacetimes is important for modeling gravitational-wave inspirals of spinning compact binaries. We build a Hamiltonian f…

Analytic Solution for the Motion of Spinning Particles in Kerr Space-Time
Viktor Skoupý, VojtÄch Witzany
The equations of motion of massive test particles near Kerr black holes are separable in Boyer-Lindquist coordinates, as established by Carter. This separability, however, is lost…

Comparing effective-one-body and Mathisson-Papapetrou-Dixon results for a spinning test particle on circular equatorial orbits around a Kerr black hole
Angelica Albertini, Viktor Skoupý, Georgios Lukes-Gerakopoulos +1
We consider a spinning test particle around a rotating black hole and compare the Mathisson-Papapetrou-Dixon (MPD) formalism under the Tulczyjew-Dixon spin supplementary condition…
