Exact BD-FRW imperfect fluid cosmologies with an electromagnetic field
It is shown that the \(k=0\) FRW metric which admits a dust solution in the Brans-Dicke theory, also admits an imperfect fluid distribution along with an electromagnetic field. The solutions are functions of time and radial coordinates and they satisfy all necessary energy and thermodynamic conditions.
