Dissipative self-gravitating systems in modified gravity

Abstract

We discuss the gravitational collapse of spherical compact objects in the background of f(R,T,Q) theory, where R represent the Ricci scalar, T is the trace of energy momentum tensor while Q≡ RμνTμν, and investigate the influence of anisotropy and heat dissipation in this scenario. We provide an analysis on the role of distinct material terms considered while studying the dynamical equation. The dynamical equation is coupled with a heat transport equation and discussed in the background of f(R,T,Q) theory of gravity. The reduction element in the density of inertial mass, is re-acquired which is based on the internal position of thermodynamics. In collation with the equivalence relation, the reduction quantity in density is similar as appeared with gravitational force. We formulate the connection of Weyl tensor with different matter variables to see the non-identical outcomes. The inhomogeneous nature of energy density is also analyzed in the framework of modified gravity.
