Light amplification by gravitational waves in scalar–tensor theories of gravity
It is shown that the amplification of a light beam by gravitational waves in scalar–tensor theories of gravity is a first order effect in the wave amplitudes. In general relativity, instead, the effect is only of second order. To appear in Astrophysical Letters and Communications Scalar–tensor theories (ST) of gravity have been considered as alternatives to general relativity (GR) for a long ti...
متن کاملQuasi-geometrical Optics Approximation in Gravitational Lensing
Abstract. The gravitational lensing of gravitational waves should be treated in the wave optics instead of the geometrical optics when the wave length λ of the gravitational waves is larger than the Schwarzschild radius of the lens mass M. The wave optics is based on the diffraction integral which represents the amplification of the wave amplitude by lensing. We study the asymptotic expansion o...
متن کاملParaxial geometrical optics for quasi-P waves: theories and numerical methods
The quasi-P wave in anisotropic solids is of practical importance in obtaining maximal imaging resolution in seismic exploration. The geometrical optics term in the asymptotic expansion for the wave characterizes the high frequency part of the quasi-P wave by using two functions: a phase (traveltime) function satisfying an eikonal equation and an amplitude function satisfying a transport equati...
متن کاملGravitational waves from the collapse and bounce of a stellar core in tensor-scalar gravity
Tensor-scalar theory of gravity allows the generation of gravitational waves from astrophysical sources, like Supernovæ, even in the spherical case. That motivated us to study the collapse of a degenerate stellar core, within tensor-scalar gravity, leading to the formation of a neutron star through a bounce and the formation of a shock. We discuss in this paper the effects of the scalar field o...
متن کامل1 Scalar gravitational waves and Einstein frame
The response of a gravitational wave detector to scalar waves is analysed in the framework of the debate on the choice of conformal frames for scalar-tensor theories. A correction to the geodesic equation arising in the Einstein conformal frame modifies the geodesic deviation equation. This modification is due to the non-metricity of the theory in the Einstein frame, yielding a longitudinal mod...
