我们表明，罗森的双度规引力理论预测发射偶极引力辐射的双星系统包含中子星，如双脉冲星PSR 1913+16，导致轨道周期的快速变化。该理论还预测了从轨道数据和近星点位移数据推断的质量的相当大的修正。我们表明，这一预测是不一致的，与观察到的上限周期变化（vertical-barP/Pvertical-bar <1.2 x 10/sup -7/ yr/sup -1/）除非系统由（a）两颗质量（约3.5 M/亚太阳/每个）相差小于0.3 M/亚太阳/，或（B）一颗质量小于0.4 M/亚太阳/的中子星星和一颗伴星，伴星必须是一颗快速旋转的白色或氦主序星星星。由于罗森的理论与所有太阳系实验的数据一致，这是对其可行性的第一次可行性测试。
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.
