The gravitational field equations are solved numerically in the Rosen bimetric theory for spherically symmetric configurations whose matter is in a state described by the polytropic equation. The integrated properties and internal structure are calculated for configurations with a polytropic index n=1, 1.5, 2, 2.5, 3, for selected values of the relativistic parameter ..cap alpha... The configurations obtained in the bimetric theory are more compact than the corresponding configurations in general relativity.
