Abstract - We have studied the behaviour of a radiating star when the interior expanding,
shearing fluid particles are traveling in geodesic motion. A systematic approach enables us to
write the junction condition as a Riccati equation. In this article we obtained two new solutions in
terms of elementary functions with assuming a separation of variables and also have discussed
the physical significance of these solutions.
