This manuscript is devoted to a general study on axial and reflection-symmetric self-gravitating sources in the background of gravity, where represents the trace of stress energy-tensor, while is the Ricci scalar. For this purpose, all the fundamental equations and notions set to carry out the general study are established. The corresponding field, as well as dynamical equations, are also exhibited. In order to discuss the thermodynamics aspects of the selected system, the modified transport equation is presented. The Weyl-tensor is utilized to evaluate the generalized version of scalar variables termed structure scalars. To produce modified scalar equations, we employ the structure scalars. The applications of our obtained results are examined on the dynamics of the source in gravity. We conclude that the modified structure scalars play an important role in the dynamics of compact objects.
