| Sumario: | Several very interesting, and not well understood, astrophysical scenarios are associated with a periodical emission of radiation from collapsed compact objects. Pulsars is the most common representative example of this phenomena. There has been reported that the rapid variation of luminosity for young supernova remmanent, generally interpreted as due to its rotation, can be alternatively explained as radial oscillations of the compact object. We used the method proposed by L. Herrera and collaborators in 1980 [1] to study General Relativistic Spheres to obtain models describing non-static radiating spheres starting from well known static equations of state. The present work including the diffusion limit for the radiation field, when inter-relations between oscillation of the surface of compact objects and their pulsating luminosity profiles are explorer. |
