Abstract
We investigate the effects of all flavor blind CP-conserving unparticle operators on 5th force experiments, stellar cooling, supernova explosions and compare the limits with each other and with those obtainable from collider experiments. In general, astrophysical bounds are considerably stronger, however they depend strongly on the dimension d of the unparticle operator. While for d = 1, 5th force experiments yield exceedingly strong bounds, the bounds from stellar and supernova cooling are more comparable for d = 2, with stellar cooling being most restrictive. Bounds on vectorial unparticle couplings are generally stronger than those on scalar ones.
