Black-holes and neutron stars in entangled relativity

TL;DR

This paper demonstrates that entangled relativity, despite its non-linear nature, closely mimics general relativity's phenomenology, providing analytical solutions for black holes and neutron stars without free parameter tuning.

Contribution

It provides the first analytical solutions for charged black holes and neutron stars within entangled relativity, showing its phenomenological similarity to general relativity.

Findings

Analytical solutions for spherically charged black holes.

Analytical and numerical solutions for neutron stars.

Phenomenology closely matches general relativity.

Abstract

I present two results that show that, despite its unusual non-linear form, the phenomenology of entangled relativity remains close to the one of general relativity -- without having any free parameter that can be fine tuned in order to facilitate this. In particular, I present the analytical solutions for spherically charged black-holes, and both the analytical and numerical solutions for neutron stars.
