Circular orbits, ISCO, periastron shift, and gravitomagnetic clock effect in Kerr field: a study using effective one-body approach

摘要

Constraint Hamiltonian dynamics is used in an effective one-body approach to study relativistic gravitational two-body system with spin-orbit interaction Radii of circular orbits, approximate location of innermost stable circular orbit (ISCO), periastron shift, and gravitomagnetic clock effect in the orbit of a non-spinning body around a slowly spinning body whose gravitational field is described by a limiting Kerr metric are derived.
