Abstract |
We discuss anisotropic charged source describing the phenomena of collapse and expansion in the context of f(R,T) theory (R is the Ricci scalar and T is the trace of Energy-momentum tensor). For this purpose, we take an auxiliary solution of the Einstein-Maxwell field equations and evaluate expansion scalar whose negative values lead to collapse and positive values give expansion. For both cases, the behavior of density, pressure, anisotropic parameter as well as mass is explored and the effects of charge as well as model parameter on these quantities are examined. It is found that the energy conditions are satisfied in both solutions for chosen values of parameters. |
