摘要
This work is devoted to study the evolutionary mechanism for anisotropic dissipative spherical system in the presence of exotic cosmic energy. The phenomenon of gravitational collapse is discussed in the framework of f(R) gravity. We apply Darmois junction conditions on the collapsing surface for which the radial pressure remains non-zero due to the presence of dark source terms. All the possible solutions are obtained through the generating function. We also define the horizon function satisfying the Riccati equation which is closely associated with the stellar characteristics and rules the star's mass to disappear due to radiations, ultimately leading to the formation of a black hole. It is theoretically predicted that the presence of f(R) dark source terms can affect the collapsing mechanism.
