  Among different measured observables of top-antitop quark pairs at hadron
colliders, the forward-backward asymmetry ($A_{\text{FB}}$) measured by the CDF
and D0 collaborations has inconsistency with the Standard Model prediction. The
measured forward-backward asymmetry grows with $t\bar{t}$ invariant mass.
Several new physics models have been proposed to explain this deviation. We
consider the consistency of the parameter space of vector unparticle (in
Flavor-Conserving scenario) with the existing $t\bar{t}$ production
measurements. In particular, we look at the total cross sections at the LHC and
Tevatron, differential cross section with $t\bar{t}$ invariant mass, and the
LHC charge asymmetry to identify the regions in parameter space that can give
the desired top $A_{\text{FB}}$ observed by the Tevatron. We show that in spite
of the intrinsic tension between the LHC charge asymmetry and $A_{\text{FB}}$,
there exists a region in the unparticle parameters space where the top
$A_{\text{FB}}$ and the LHC charge asymmetry are satisfied simultaneously.
Finally, we show that the consistent region with $t\bar{t}$ observables is
consistent with the constraints coming from the dijet resonance searches.
