Causal Bulk Viscous LRS Bianchi I Models With Variable Gravitational and Cosmological “Constant”
نویسندگان
چکیده
In this paper we have investigated an LRS Bianchi I anisotropic cosmological model of the universe by taking time varying G and Λ in the presence of bulk viscous fluid source described by full causal non-equilibrium thermodynamics. We obtain a cosmological constant as a decreasing function of time and for m,n > 0, the value of cosmological “constant” for this model is found to be small and positive which is supported by the results from recent supernovae observations.

متن کاملFull Causal Bulk Viscous Lrs Bianchi I with Time Varying Constants
In this paper we study the evolution of a LRS Bianchi I Universe, filled with a bulk viscous cosmological fluid in the presence of time varying constants " but " taking into account the effects of a c-variable into the curvature tensor. We find that the only physical models are those which " constants " G and c are growing functions on time t, while the cosmological constant Λ is a negative dec...
متن کاملBulk 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...
متن کاملA New Class of LRS Bianchi Type VI0 Universes with Free Gravitational Field and Decaying Vacuum Energy Density
A new class of LRS Bianchi type VI0 cosmological models with free gravitational fields and a variable cosmological term is investigated in presence of perfect fluid as well as bulk viscous fluid. To get the deterministic solution we have imposed the two different conditions over the free gravitational fields. In first case we consider the free gravitational field as magnetic type whereas in sec...
متن کاملBulk 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
