Quasi-homologous evolution of relativistic stars

This paper studies the evolutionary mechanism of the relativistic spherically symmetric spacetime who is coupled with both radiating and non-radiating matter content in f ( R , T ) gravity. This modeled system is assumed to obey the constraint of minimal complexity having areal radius velocity to be proportional to the areal radius, i.e., quasi-homologous condition. The corresponding few exact analytical solutions are examined with some realistic background. Our few models described the emergence of Minowskian cavity around the center of the relativistic spherical structure. We also calculated the structure scalars in modified gravity that are gained by splitting the Riemann tensor orthogonally. The structure scalar Y T F e f f is found to the complexity factor. Various realistic applications of our calculated models in relativistic astrophysics are described. •Evolutionary mechanism of relativistic star will be studied in f ( R , T ) gravity.•It obeys the constraint of minimal complexity with quasi-homologous condition.•Some exact analytical solutions are explored with realistic background.
