On uniqueness of non-vacuum stationary axisymmetric type D spacetime
Hiroaki Nakajima, Ya Guo, Wenbin Lin
We study a family of the non-vacuum stationary axisymmetric type D metrics, where the two principal null directions are geodesic and shearfree. It is demonstrated that the conforma…

Teukolsky-like equations with various spins in a deformed Kerr spacetime
Hiroaki Nakajima, Ya Guo, Wenbin Lin
We study the wave equations with the various spins on the background of the Kerr metric deformed by a function of the radial coordinate, on which background we have studied the gra…
