The hypothesis of an alternative way obtaining gravitational waves is the physical motivation this article. Using linear field approximation and a symmetry transformation affine connection, new equations gauge conditions have been obtained. Solutions to these considered in empty space wave zone, both them oscillation amplitudes their solutions are attenuated exponentially. We expect that can be...

Andersson et al. and Bildsten proposed that the spin of accreting neutron stars is limited by removal of angular momentum by gravitational radiation which increases dramatically with the spin frequency of the star. Both Bildsten and Andersson et al. argued that the r−modes of the neutron star for sufficiently quickly rotating and hot neutron stars will grow due to the emission of gravitational ...

We show that if the visible universe is a membrane embedded in a higher-dimensional space, particles in uniform motion radiate gravitational waves because of spacetime lumpiness. This phenomenon is analogous to the electromagnetic diffraction radiation of a charge moving near to a metallic grating. In the gravitational case, the role of the metallic grating is played by the inhomogeneities of t...

We have developed a 3-D Eulerian hydrodynamics code to model sources of gravitational radiation. The code is written in cylindrical coordinates (̟, z, φ) and has moving grids in the ̟ and z-directions. We use Newtonian gravity and calculate the gravitational radiation in the quadrupole approximation. This code has been tested on a variety of problems to verify its accuracy and stability, and the ...

The gravitational analog of the electromagnetic Poynting vector is constructed using the field equations of general relativity in the Hilbert gauge. It is found that when the gravitational Poynting vector is applied to the solution of the linear mass quadrupole oscillator, the correct gravitational quadrupole radiation flux is obtained. Further to this, the Maxwell-like gravitational Poynting v...

The consequences of spin-rotation-gravity coupling are worked out for linear gravitational waves. The coupling of helicity of the wave with the rotation of a gravitational-wave antenna is investigated and the resulting modifications in the Doppler effect and aberration are pointed out for incident high-frequency gravitational radiation. Extending these results to the case of a gravitomagnetic f...

It is shown that linearized gravitational radiation confined in a cavity can achieve thermal equilibrium if the mean density of the radiation and the size of the cavity satisfy certain constraints. Is it possible, in principle, to confine gravitational radiation in a box, for a time long enough for it to achieve thermal equilibrium? This issue has been investigated before by various authors [1,...

Grasers based on a stimulated emission of gravitational radiation by relativistic charged particle beams in external fields and on conversion of laser radiation into grav-itational one in the magnetic fields as well as detectors are discussed. It was pointed out on a scheme where the gravitational radiation is not accompanied by an useless inaccessible by a value average power of the electromag...
