Teukolsky-like equations with various spins in spherically symmetric spacetime
Ya Guo, Hiroaki Nakajima, Wenbin Lin
We study the wave equations with various spins on the background of the general spherically symmetric spacetime. We obtain the unified expression of the Teukolsky-like master equat…

Teukolsky-like equations in a non-vacuum axisymmetric type D spacetime
Ya Guo, Hiroaki Nakajima, Wenbin Lin
We study an axisymmetric metric satisfying the Petrov type D property with some additional ansatze, but without assuming the vacuum condition. We find that our metric in turn becom…
