Astrophysical constraints on unparticle-inspired models of gravity

TL;DR

This paper uses stellar dynamics to place constraints on unparticle-inspired gravity models, showing that certain parameter ranges are limited when the energy scale exceeds 1 TeV and the unparticle dimension is near one.

Contribution

It provides the first astrophysical constraints on ungravity models, linking stellar dynamics with unparticle physics parameters.

Findings

Bounds on ungravity parameters for energy scale ≥ 1 TeV

Constraints are tight when unparticle dimension is close to one

Astrophysical data limits unparticle-inspired gravity models

Abstract

We use stellar dynamics arguments to constrain the relevant parameters of ungravity inspired models. We show that resulting bounds do constrain the parameters of the theory of unparticles, as far as its energy scale satisfies the condition $\Lambda \geq 1 TeV$ and $d$ is close to unity.
