Collapsing and Expanding Observation of Anisotropic Charged Source in f(R,T) Gravity
Journal Title: Acadlore Transactions on Applied Mathematics and Statistics - Year 2024, Vol 2, Issue 2
Abstract
In the present work we investigate the collapsing and expanding solutions of the Einstein’s field equation of anisotropic fluid in spherically symmetric space-time and with charge within the framework of f(R, T) theory, where R denotes the Ricci scalar and T denotes the trace of the energy−momentum tensor. We also evaluate the expansion scalar, whose negative values result in collapse and positive values yield expansion. We analyzed the impacts of charge in f(R, T) theory on the density and pressure distribution of the collapsing and expanding fluid and noticed the involvement of anisotropic fluid in the process of collapsing and expanding with charge in f(R, T). Furthermore, the definition of mass function has been used to analyse the condition for the trapped surface, and it has been found that in this case there is only one horizon. In all scenarios, the effects of coupling parameters λ and q have been thoroughly examined. Additionally, we have created graphs representing pressures, anisotropy, and energy density in f(R, T) theory and check the effect of charge on these quantities.
