Spinning Wormholes in Scalar-Tensor Theory

TL;DR

This paper explores spinning wormholes within scalar-tensor theories, examining how scalarization affects their structure, existence, and properties, including the possibility of multiple throats and equators depending on the frame and coupling function.

Contribution

It introduces the concept of scalarized spinning wormholes in scalar-tensor theory and analyzes their domain of existence and structural features.

Findings

Scalarized wormholes can have multiple throats and equators in the Jordan frame.

Scalarization influences the wormholes' properties and domain of existence.

The structure varies between Jordan and Einstein frames depending on the coupling function.

Abstract

We consider spinning generalizations of the Ellis wormhole in scalar-tensor theory. Analogous to other compact objects these wormholes can carry a non-trivial scalarization. We determine the domain of existence of the scalarized wormholes and investigate the effect of the scalarization on their properties. Depending on the choice of the coupling function, they may possess multiple throats and equators in the Jordan frame, while possessing only a single throat in the Einstein frame.
