11. Until then, their gravitational radiation would be comparable to that of a neutron star binary. 12. Physically, these represent purely gravitational radiation propagating along the null rays \ partial _ v. 13. Changing mass-current multipoles can also give off gravitational radiation . 14. :Strictly speaking the only non-electromagnetic radiation is gravitational radiation . 15. Angular momentum is also lost in the gravitational radiation . 16. Two neutron stars rotating rapidly around one another gradually lose energy by emitting gravitational radiation . 17. Relativity predicts that over time a binary system's orbital energy will be converted to gravitational radiation . 18. :: I think both of you are confusing gravitational fields with gravitational radiation ( waves ). 19. The mass quadrupole, however, can change in time, and is the lowest-order contribution to gravitational radiation . 20. Hessels goes on to speculate that gravitational radiation from the pulsar might be detectable by LIGO.
