Vacuumless cosmic strings in Brans - Dicke theory
نویسنده
چکیده
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.

Global Monopoles in Brans-Dicke Theory of Gravity
The gravitational field of a global monopole in the context of Brans-Dicke theory of gravity is investigated. The space-time and the scalar field generated by the monopole are obtained by solving the field equations in the weak field approximation. A comparison is made with the corresponding results predicted by General Relativity. Electronic address: [email protected] 1 Monopoles resulting ...
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.

متن کاملCylindrical sources in full Einstein and Brans-Dicke gravity
It was shown by Hiscock that the energy-momentum tensor commonly used to model local cosmic strings in linearized Einstein gravity can be extended and used in the full theory, obtaining a metric in the exterior of the source with the same deficit angle. Here we show that this tensor is an exception within a family for which a static solution does not exist in full Einstein nor in Brans-Dicke gr...
متن کاملCircular Cosmic String Loop in Brans-Dicke Theory
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 parame...
متن کاملCosmic Microwave Background Temperature and Polarization Anisotropy in Brans-Dicke Cosmology
We develop a formalism for calculating cosmic microwave background (CMB) temperature and polarization anisotropies in cosmological models with BransDicke gravity. We then modify publicly available Boltzmann codes to calculate numerically the temperature and polarization power spectra. Results are illustrated with a few representative models. Comparing with the generalrelativistic model with the...
