Circular Cosmic String Loop in Brans-Dicke Theory
نویسندگان
چکیده
The gravitational eld of a stationary circular cosmic string loop, externally supported against collapse, is investigated in the context of Brans-Dicke theory in the weak eld approximation of the eld equations. The solution is quasi-conformally related to the corresponding solution in Einstein's General Relativity(GR) and goes over to the corresponding solution in GR when the Brans-Dicke parameter ! becomes in nitely large.

A ug 1 99 8 Superconducting cosmic string in Brans - Dicke theory
In the present work, the gravitational field of superconducting cosmic string has been investigated in the context of Brans-Dicke theory of gravity. We have presented two kind of solutions for the spacetime in the far field zone of the string. When the B-D scalar field is switched off, one of the solutions reduces to the solution earlier obtained by Moss and Poletti in General Relativity.

متن کاملVacuumless cosmic strings in Brans - Dicke theory
The gravitational fields of vacuumless global and gauge string have been studied in Brans-Dicke theory under the weak field assumption of the field equations. It has been shown that the global vacuumless string has a repulsive gravitational effect whereas the gauge string has an attractive gravitational effect in BD theory.
متن کاملString and Brans-Dicke Theories
We present the static, spherically symmetric solutions of the low energy d = 4 string. They form a simple generalisation of the Schwarzschild solution and describe the gravitational field of a spherical star in perturbative string theory. If the Robertson parameter γ is different from one, these solutions describe singular objects with naked singularities at their horizons, and whose Hawking te...
متن کاملWiggly Strings in Linearized Brans-dicke Gravity
The metric around a wiggly cosmic string is calculated in the linear approximation of Brans-Dicke theory of gravitation. The equations of motion for relativistic and nonrelativistic particles in this metric are obtained. Light propagation is also studied and it is shown that photon trajectories can be bounded.
