Description:
This manuscript explores the unstable/stable regimes of self-gravitating matter configuration of spherical star due to the impact of modification in gravity model as studied in f ( R , T , R T ) theory. We have designed our analysis by keeping the system in hydrostatic equilibrium initially and then moved it into the non-static phase. The dynamical as well as collapse equations are established by using the field equations and Bianchi identities. Using a particular equation of state, we have checked the effects of adiabatic index on the unstable/stable regions of the collapsing model. The influence of dark source terms is also examined with flat background metric and with some known profile of the geometry. We found that the extra curvature invariants of f ( R , T , R T ) gravity has greatly modified collapse rate due to their repulsive nature.
