Abstract :

In this paper, we study the transport equation which provide the information about the transfer of mass, heat and momentum during the gravitational collapse of massive stars. We adopt the modified theories of gravity and examine the process of energy transport and its effects on the collapsing process. We discuss how such theories may incorporated mathematically into the analysis and control of the dynamics of a complex system. The transport equation governs the dissipative fluxes and their associated quantities like temperature, relaxation time and thermal conductivity. It helps to construct physically viable models of radiating stars. We also develop the dynamical equations and coupled with transport equation. We discuss how inertia of heat causes a decrease in the inertial and gravitational mass densities and hence effect the outcome of the gravitational collapse. We obtained three cases depending on a physical factor and on its positive and negative value. Positive value yields the gravitational collapse of massive stars whereas negative value yields the formation of white dwarf.
