Dynamics of extended bodies in a Kerr spacetime with spin-induced quadrupole tensor
Dynamics of extended bodies in a Kerr spacetime with spin-induced quadrupole tensor
The features of equatorial motion of an extended body in Kerr spacetime are investigated in the framework of the Mathisson-Papapetrou-Dixon model. The body is assumed to stay at quasiequilibrium and respond instantly to external perturbations. Besides the mass, it is completely determined by its spin, the multipolar expansion being truncated …
