Abstract

We use stellar dynamics arguments to constrain the relevant parameters of unparticle-inspired models of gravity. We show that resulting bounds do constrain the parameters of the theory of unparticles, as far as its energy scale satisfies the condition \ensuremathΛ_U\ensuremath≥1 TeV and d_U is close to unity.
