Stable causality of Black Saturns

TL;DR

This paper proves that Black Saturn solutions in general relativity are stably causal within their outer communication domain, ensuring no causal anomalies occur there.

Contribution

It establishes the stable causality of Black Saturn spacetimes, a significant step in understanding their causal structure.

Findings

Black Saturns are stably causal on the closure of the domain of outer communications

The proof confirms the absence of causal violations in these spacetimes

Abstract

We prove that the Black Saturns are stably causal on the closure of the domain of outer communications.
