Non-supersymmetric black rings as thermally excited supertubes

TL;DR

This paper constructs a family of non-supersymmetric black ring solutions in supergravity, modeling thermally excited supertubes with multiple charges and dipoles, advancing understanding of non-supersymmetric black objects.

Contribution

It introduces a seven-parameter family of supergravity solutions describing non-supersymmetric black rings and tubes with multiple charges and dipoles, extending the known solutions to include thermal excitations.

Findings

Black rings have regular horizons and non-zero temperature.

Solutions describe thermally excited supertubes with specific charge and dipole configurations.

A more general family is needed for thermal excitations near supersymmetry.

Abstract

We construct a seven-parameter family of supergravity solutions that describe non-supersymmetric black rings and black tubes with three charges, three dipoles and two angular momenta. The black rings have regular horizons and non-zero temperature. They are naturally interpreted as the supergravity descriptions of thermally excited configurations of supertubes, specifically of supertubes with two charges and one dipole, and of supertubes with three charges and two dipoles. In order to fully describe thermal excitations near supersymmetry of the black supertubes with three charges and three dipoles a more general family of black ring solutions is required.
