| Abstract | Abstract Starting from the Kerr–Schild coordinates, a set of horizon penetrating harmonic coordinates for the Kerr metric is worked out and exhibit the explicit form of the whole metric. As a validity check on the calculations, the multipole expansion of the Kerr metric is then derived from the harmonic formulation. The resemblance of the geometry of the harmonic slicing with the ‘1 + log’ slicing and the generalized harmonic gauge in numerical relativity is then further discussed. Together with its horizon penetrating structure, the harmonic formulation is well suited for the numerical simulation of astrophysical electromagnetic phenomena, like for instance the Blanford–Znajek process, in the vicinity of a supermassive black hole. |
