- Abstract
We prove smoothness of the domain of outer communications (d.o.c.) of the
Black Saturn solutions of Elvang and Figueras. We show that the metric on the d.o.c.
extends smoothly across two disjoint event horizons with topology RxS3 and RxS1xS2.
We establish stable causality of the d.o.c. when the Komar angular momentum of the
spherical component of the horizon vanishes, and present numerical evidence for stable
causality in general.
