| Abstract: | We study the evolution of spherically symmetric radiating fluid distributions using the effective variables method, implemented
ab initio in Schwarzschild coordinates. To illustrate the procedure and to establish some comparison with the original method, we integrate
numerically the set of equations at the surface for two different models. The first model is derived from the Schwarzschild
interior solution. The second model is inspired in the Tolman VI solution. |
