Spin precession in general stationary and axisymmetric spacetimes
Shaofei Xu, Junji Jia
This paper investigates the spin precession of test particles moving in the equatorial plane of general stationary and axisymmetric spacetimes using the Mathisson-Papapetrou-Dixon…

Dragging of the particle spin and spin-spin coupling effect on its periapsis shift
Shaofei Xu, Junji Jia
The periapsis shift (PS) of spinning test particles in the equatorial plane of arbitrary stationary and axisymmetric spacetime is studied using the post-Newtonian method. The resul…

Periapsis precession in general stationary and axisymmetric spacetimes
Jinhong He, Shaofei Xu, Junji Jia
This work studies the periapsis shift in the equatorial plane of arbitrary stationary and axisymmetric spacetimes. Two perturbative methods are systematically developed. The first…
