... . This shows the status of a one~imensional numerical model of SN1987A at a time when its predictions for detailed spectral behavior debate Mom observations (Lupy 1987~.

... because it uses an average opacity rather than We radially varying opacity of the numerical models. Apparently me recombination wave does not move Award through the abundance layers in complete synchronization.

... of order ~ip/p~ ~ 1 occur along many lmes of sight from the center. Because this directly modifies the attenuation length, which itself appears in an exponential function, the X-ray and gamma ray light curves are strongly affected, making them earlier and flatter, as needed.

... A 15 M<3 B3 supergiant presupernova structure with a radius of 3 X 1012 cm and a fairly realistic explosion (fitting the early light curve of 1987A) were used.

... This effect is in addition to Mat of clumping on gamma ray escape, which they speculate may improve agreement with observation. Quantitative estimates require knowledge of the actual three-dimensional structure.
