We report on solutions to the Einstein field equations representing spherically symmetric, shear-free spacetimes with heat flux. The source matter for all of these spacetimes satisfies an equation of state of the barotropic form p = αρ where p and ρ are the pressure and density of the matter fluid while α is a constant. As an application, we model the collapse of a shear-free, radiating star which dissipates energy in the form of a radial heat flux. The heat flows from the hotter parts of the… CONTINUE READING
