| Sumario: | Assuming the existence of a polarization produced by Thompson scattering, as suggested by the observations, a model has been computed for the optically thin layers of SN 1987A. Supposing that the isodensities in this region are oblate ellipsoids, we found the equation that describes the observable polarization as a function of its parameters. If we assumed that the inclination of the axis of symmetry and the eccentricity of the envelope are constant and using a model for the mass ejection, we were able to study the evolution of the size and density of the region as a function of time. |
