Query: Behaviour of Charged Collapsing Fluids after Hydrostatic Equilibrium in
  R^n Gravity   The purpose of this paper is to study the transport equation and its coupling
with Maxwell equation in the framework of R^n gravity. Using
Muller-Israel-Stewart theory for the conduction of dissipative fluids, we
analyze the temperature, heat flux, viscosity and thermal conductivity in the
scenario of relaxation time. All these thermodynamical variables are appeared
in the form of a single factor whose influence is discussed on the evolution of
relativistic model for the heat conducting collapsing star.
