Outline of Final Research Achievements |
We considered the parameter estimation accuracy of gravitational waves from coalescing compact binaries with a network of laser interferometric gravitational wave detectors. Especially, we investigated the effect of the higher order modulation of gravitational waves from binaries. We found that the use of wave forms which contain higher order modulation effects are most effective to determine the inclination angle of orbital plane. We also found that, if we could detect gravitational waves from coalescing compact binaries which are associated with short gamma ray burst, we can determine the inclination angle of binaries's orbital plane with accuracy of 3 to 7 degree. We computed the perturbation of gravitational fields produced by a rotating mass ring on the equatorial plane around a black hole. We used the Teukolsky equation and the CCK formalizm to obtain the gravitational fields. We obtained various useful technical information in the CCK method.
