An Interacting model of Dark Energy in Brans-Dicke theory
  In this paper it is shown that in non-minimally coupled Brans-Dicke theory
containing a self-interacting potential, a suitable conformal transformation
can automatically give rise to an interaction between the normal matter and the
Brans-Dicke scalar field. Considering the scalar field in the Einstein frame as
the quintessence matter, it has been shown that such a non-minimal coupling
between the matter and the scalar field can give rise to a late time
accelerated expansion for the universe preceded by a decelerated expansion for
very high values of the Brans-Dicke parameter $\omega$. We have also studied
the observational constraints on the model parameters considering the Hubble
and Supernova data.
