Scientific paper

The authors briefly review possible systematic limitations to inferred general relativity tests in binary pulsar systems, then propose a new mechanism whereby orbital energy can be dissipated. The basic idea is that tidal pressure fluctuations can drive the electron-proton vs. neutron density away from equilibrium, and the concomitant neutrino (or antineutrino) emission represents an orbital energy dissipation. Of the total orbital energy loss rate, the authors estimate the fractional contribution of this mechanism as 8×10-6, whereas the observational accuracy is at the level of 7×10-3, and agrees with the predicted rate of gravitational radiation.
