DOI: 10.1088/1361-6382/aacb75
Abstract: It is not currently known how to put the Kerr spacetime metric into the so-called Gordon form, although the closely related Kerr-Schild form of the Kerr metric is well known. A Gordon form for the… read more here.

DOI: 10.1088/1361-6382/ab6860
Abstract: The nonlinear superposition of the delta-metric and the Kerr metric results in delta-Kerr metric that represents a deformed Kerr black hole with delta = 1 + q, where q > 0 is proportional to the… read more here.

DOI: 10.1103/physrevd.105.064036
Abstract: We construct a new type of Chandrasekhar transformation in Kerr spacetime using the different tortoise coordinate, which is useful for exact analysis to study Teukolsky equation with arbitrary frequency. We also give the interpretation of… read more here.

DOI: 10.1103/physrevd.95.084042
Abstract: In this paper, we study the quasi-local energy (QLE) and the surface geometry for Kerr spacetime in the Boyer-Lindquist coordinate without taking the slow rotation approximation. We also consider in the region $r r_{k}(a)$, the… read more here.

DOI: 10.1103/physrevd.96.024053
Abstract: We show that, contrary to what is usually claimed in the literature, the zero mass limit of Kerr spacetime is not flat Minkowski space but a spacetime whose geometry is only locally flat. This limiting… read more here.

Gravitational self-force corrections to gyroscope precession along circular orbits in the Kerr spacetime

DOI: 10.1103/physrevd.98.104062
Abstract: We generalize to Kerr spacetime previous gravitational self-force results on gyroscope precession along circular orbits in the Schwarzschild spacetime. In particular we present high order post- Newtonian expansions for the gauge invariant precession function along… read more here.
