We show that Rosen's bimetric theory of gravity predicts the emission of dipole gravitational radiation from binary systems containing neutron stars, such as the binary pulsar PSR 1913+16, that causes rapid changes in orbital period. The theory also predicts sizable corrections to masses inferred from orbital data and periastron-shift data. We show that this prediction is inconsistent with the observed upper limit on period changes (vertical-barP/Pvertical-bar <1.2 x 10/sup -7/ yr/sup -1/) unless the system consists of (a) two neutron stars whose masses (approx.3.5 M/sub sun/ each) differ by less than 0.3 M/sub sun/, or (b) a neutron star of mass less than 0.4 M/sub sun/ and a companion which must be a rapidly rotating white dwarf or a helium main-sequence star. Because Rosen's theory agrees with all solar-system experiments to data, this represents the first feasible test of its viability.
