Variable Modified Chaplygin Gas and Accelerating Universe
In this letter, I have proposed a model of variable modified Chaplygin gas and shown its role in accelerating phase of the universe. I have shown that the equation of state of this model is valid from the radiation era to quiessence model. The graphical representations of statefinder parameters characterize different phase of evolution of the universe. All results presented in the letter concer...
متن کاملChaplygin Gas Cosmology Predicts Only 'dusty' Universe
We consider a new approach for Chaplygin gas cosmology, in which the relativistic formulation of Chaplygin matter is of crucial importance. Specifically, the dynamical content of this matter induces a generalizd energy conservation principle. Our results show that (for all times) the universe consists of a novel form of matter with dust like density (∼ (volume) −1) and negative pressure, that i...
متن کاملWormholes supported by phantom-like modified Chaplygin gas
We have examined the possible construction of a stationary, spherically symmetric and spatially inhomogeneous wormhole spacetime supported by the phantom energy. The later is supposed to be represented by the modified Chaplygin gas equation of state. The solutions so obtained satisfy the flare out and the asymptotic flatness conditions. It is also shown that the averaged null energy condition h...
متن کاملCrossing the Phantom divide line in the Chaplygin gas model
The rôle of the interaction in crossing the phantom divide line in the Chaplygin gas model is discussed. We obtain some general properties of the interactions that allow the model to arrive at phantom divide line. We show that these properties put some conditions on the ratio of dark matter to dark energy density. PACS: 98.80.-k, 98.80.Jk
متن کاملRole of Modified Chaplygin Gas in Accelerated Universe
Recent observations of the luminosity of type Ia supernovae indicate [1, 2] an accelerated expansion of the universe and lead to the search for a new type of matter which violate the strong energy condition ρ + 3p < 0. The matter consent responsible for such a condition to be satisfied at a certain stage of evolution of the universe is referred to as dark energy. There are different candidates ...
