Astrophysical Constraints on the Bumblebee Model

TL;DR

This paper investigates how the Bumblebee model, which involves spontaneous Lorentz symmetry breaking, affects astrophysical bodies and derives constraints on its parameters based on modified equations of motion.

Contribution

It provides the first detailed analysis of the Bumblebee model in spherically symmetric astrophysical contexts and derives observational constraints on its parameters.

Findings

Constraints on Bumblebee model parameters derived from astrophysical data

Modified equations of motion for spherically symmetric bodies in the model

Perturbative analysis of Lorentz symmetry breaking effects

Abstract

In this work the Bumblebee model for spontaneous Lorentz symmetry breaking is considered in the context of spherically symmetric astrophysical bodies. A discussion of the modified equations of motion is presented and constraints on the parameters of the model are perturbatively obtained.
