Query: The radiative decay $D^0 \to \bar{K}^{*0} \gamma$ with vector meson
  dominance   Motivated by the experimental measurements of $D^0$ radiative decay modes we
have proposed a model to study the $D^0\to \bar{K}^{*0}\gamma$ decay, by
establishing a link with $D^0\to \bar{K}^{*0}V$ $(V=\rho^0,\, \omega)$ decays
through the vector meson dominance hypothesis. In order to do this properly, we
have used the Lagrangians from the local hidden gauge symmetry approach to
account for $V\gamma$ conversion. As a result, we have found the branching
ratio $\mathcal{B}[D^0\to \bar{K}^{*0}\gamma] =(1.55 - 3.44)\times 10^{-4}$,
which is in fair agreement with the experimental values reported by Belle and
Babar collaborations.
