  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 $Q\equiv R_{\mu\nu}T^{\mu\nu}$, 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.
