TL;DR

This paper explores oscillatons, which are regular, asymptotically flat solutions of the Einstein-Klein-Gordon equations, and visualizes their behavior in non-linear gravity through a conformal mapping.

Contribution

It introduces a Legendre transformation to analyze oscillatons within non-linear gravity, providing a new perspective on their structure.

Findings

Oscillatons are shown to be globally regular and asymptotically flat.

A Legendre transformation helps visualize their behavior in non-linear gravity.

The scalar field absorption via conformal mapping offers new insights.

Abstract

Oscillatons are solutions of the coupled Einstein-Klein-Gordon (EKG) equations that are globally regular and asymptotically flat. By means of a Legendre transformation we are able to visualize the behaviour of the corresponding objects in non-linear gravity where the scalar field has been absorbed by means of the conformal mapping.
