Dynamics of non-adiabatic charged spherical gravitational collapse in [formula omitted] gravity

Abstract

In current manuscript, we have analyzed the effects of charge on non-adiabatic gravitational collapse dynamics in the framework of f(R,T) gravity utilizing Misner-Sharp approach. The modified field equations of f(R,T) gravity have been evaluated for the spherically symmetric sphere spacetime. The deviation of total energy inside the spacetime of the gravitating compact object has been determined by Misner and Sharp mass function. The key role of some important factors appeared in dynamical equation are investigated in detail. The Bianchi identities affected by electromagnetic field are formulated in f(R,T) gravity to find dynamical equation for compact object. Furthermore, we coupled the causal heat transport equation obtained in the context of Mu¨ller-Israel-Stewart formalism with dynamical equation. To see the more physical results, we have applied a linear model of f(R,T) gravity. Also we have investigated the impacts of matter-curvature coupling constant λ on gravitational forces and inertial mass density. It diminishes the significance of the gravitational force which result to slow down the collapse rate. The proposed applications which are directly related to astrophysical scenarios have been widely discussed.
