Abstract EN
We analyse the gravitational behaviour of a relativistic heat conducting fluid in a shear-free spherically symmetric spacetime.
We show that the isotropy of pressure is a consistency condition which realises a second order nonlinear ordinary differential equation with variable coefficients in the gravitational potentials.
Several new classes of solutions are found to the governing equation by imposing various forms on one of the potentials.
Interestingly, a complex transformation leads to an exact solution with only real metric functions.
All solutions are written in terms of elementary functions.
We demonstrate graphically that the fluid pressure, energy density, and heat flux are well behaved for the model, and the model is consistent with a core-envelope framework.
