New generalized nonspherical black hole solutions

TL;DR

This paper provides numerical evidence for new static black hole solutions with nonspherical horizons in higher dimensions, extending known five-dimensional black rings and related configurations, and discusses potential rotating generalizations.

Contribution

It introduces new higher-dimensional static black hole solutions with nonspherical horizons supported by conical singularities, expanding the landscape of known black hole topologies.

Findings

Existence of static black holes with nonspherical horizons in $d extgreater=6$ dimensions.

These solutions are higher-dimensional analogs of black rings, dirings, and black Saturn.

Discussion of possible rotating versions of these solutions.

Abstract

We present numerical evidence for the existence of several types of static black hole solutions with a nonspherical event horizon topology in $d\geq 6$ spacetime dimensions. These asymptotically flat configurations are found for a specific metric ansatz and can be viewed as higher dimensional counterparts of the $d=5$ static black rings, dirings and black Saturn. Similar to that case, they are supported against collapse by conical singularities. The issue of rotating generalizations of these solutions is also considered.
