ON ZERO-MASS SCALAR FIELD INTERACTING WITH THE GRAVITATIONAL FIELD IN PRESENCE OF CHARGED PERFECT FLUID IN SPHERICALLY SYMMETRIC CONFORMALLY FLAT SPACE-TIMES

摘要

Considering conformally flat non-static spherically symmetric metric the problem of Zero-Mass Scalar field interacting with charged perfect fluid distributions has been studied. Exact Solutions corresponding to an equation of state between the pressure and the density (p = εp) have been obtained. Physical distributions such as dust distribution, stiff fluid distribution, disordered distribution of radiation and matter distribution in inter-nebular space etc. are discussed as particular cases of the above general case (p = εp ). Also we find as the implications of Physics that for the conformally flat spherically symmetric metric the magnetic field components F_(23) cannot survive while the only electromagnetic components F_(14)can survive interacting with the perfect fluid distribution.
