Scalarized Black Holes

TL;DR

This paper explores scalarized black holes arising from higher curvature modifications to gravity, examining their properties and how they differ from classical solutions in General Relativity.

Contribution

It provides a comprehensive discussion of various scalarized black hole solutions and their distinctive features in theories with higher curvature terms.

Findings

Scalarized black holes exhibit unique properties compared to classical black holes.

Higher curvature terms like Gauss-Bonnet induce scalarization effects.

Different types of scalarized black holes have been characterized.

Abstract

Black holes represent outstanding astrophysical laboratories to test the strong gravity regime, since alternative theories of gravity may predict black hole solutions whose may differ distinctly from those of General Relativity. When higher curvature terms are included in the gravitational action as, for instance, in the form of the Gauss-Bonnet term coupled to a scalar field, scalarized black holes result. Here we discuss several types of scalarized black holes and some of their properties.
