چکیده مقاله:

Spatially homogeneous Bianchi type-II, VIII and IX anisotropic, as well as isotropic cosmological models can be obtained in a scalar tensor theory of gravitation proposed by Saez and Ballester (1986) when the source for energy momentum tensor is a bulk viscous fluid containing one-dimensional cosmic strings. All the models obtained and presented here are expanding, non-rotating and accelerating. Also, some important features of the models thus obtained have been discussed.

Bulk Viscous Bianchi Type VI0 Cosmological Model in the Self-creation Theory of Gravitation and in the General Theory of Relativity

In the second self-creation theory of gravitation and in the general theory of relativity, Bianchi type VI0 cosmological model in the presence of viscous fluid is studied. An exact solution of the field equations is given by considering the cosmological model yields a constant decelerations parameter q=constant and the coefficients of the metric are taken as A(t)=[c1t+c<su...

Viscous String Cosmological Models in Alternative Theory of Gravity

Recently observational data indicates that the discrepancy arises at late time, when the age of the universe is some billions years. In this context the Friedmann-RobertsonWalker model is a unique correspondence between the expansion rate and the distance scale. Although general theory of relativity (GTR) is the most suitable theory for describing universe as a whole, but still there are some p...

Bulk Viscous Cosmological Models in Barber’s Second Self Creation Theory

Several modification of Einstein’s general relativity have been proposed and extensively studied so far by many cosmologists to unify gravitation and many other effects in the universe. Barber 1 has produced two continuous self-creation theories by modifying the Brans-Dicke theory and general relativity. The modified theories create the universe out of self-contained gravitational and matter fi...

Bulk Viscous Cosmological Models in General Relativity

A new class of exact solutions of Einstein’s field equations with bulk viscous fluid for an LRS Bianchi type-I spacetime is obtained by using deceleration parameter as variable. The value of Hubble’s constant H0 is found to be less than half for non-flat model and is equal to 1.3 for flat model which are of the physical interest. PACS No. : 04.20.-q, 98.80.-k

Plane-symmetric Inhomogeneous Bulk Viscous Cosmological Models with Variable Λ

In recent years cosmological models exhibiting plane symmetry have attracted the attention of various authors. At the present state of evolution, the universe is spherically symmetric and the matter distribution in it is isotropic and homogeneous. But in its early stages of evolution, it could have not had a smoothed out picture. Close to the big bang singularity, neither the assumption of sphe...

Strange quark matter attached to string cloud in general scalar tensor theory of gravitation

Bianchi type-VI0 space time with strange quark matter attached to string cloud in Nordtvedt [1] general scalar tensor theory of gravitation with the help of a special case proposed by Schwinger [2] is obtained. The field equations have been solved by using the anisotropy feature of the universe in the Bianchi type-VI0 space time. Some important features of the model, thus obtained, have been di...
