AbstractThe motion of spinning test particles around a traversable wormhole is investigated using the Mathisson-Papapetrous-Dixon equations, which couple the Riemann tensor with the antisymmetric tensor S-alpha beta, related to the spin of the particle. Hence, we study the effective potential, circular orbits, and innermost stable circular orbit (ISCO) of spinning particles. We found that the spin affects significantly the location of the ISCO, in contrast with the motion of nonspinning particles, where the ISCO is the same in both the upper and lower universes. On the other hand, since the dynamical four-momentum and kinematical four-velocity of the spinning particle are not always parallel, we also consider a superluminal bound on the particles motion. In the case of circular orbits at the ISCO, we found that the motion of particles with an adimensional spin parameter lower (greater) than s = -1.5 (1.5) is forbidden. The spin interaction becomes important for Kerr black hole orbiting super massive wormholes (SMWH). The motion of spinning test particles around a rotating wormhole is in process, and we will present it in a new manuscript soon.
