Abstract.

In this paper, we study the non-static spherically symmetric solution in the scenario of \(f(R,T,Q)\) gravity (R stands for the scalar curvature, T denotes the trace component of \(T_{ab}\) and \(Q=R_{ab}T^{ab}\)). The junction conditions are developed by taking interior and exterior metrics. For a specified model of this gravity, we formulate the field equations using a perfect fluid and discuss the solution for the dust case with constant scalar curvature and trace of the energy-momentum tensor. We evaluate the mass function for this solution and discuss the mass-radius relation as well as the surface redshift of the star. These show compatible results for suitable choice of parameters.
