This paper presents new calculations of instabilities, mixing, and clumping in the ejecta of SN 1987A, which are an extension of calculations published of Arnett et al. (1989) and which make it possible to differentiate between physical and numerical effects. It is shown that perturbations of physically reasonable amplitude provide sufficient mixing and clumping to explain the earlier than expected observations of X-rays and gamma rays and the shape of the SN 1987A light curve. It is also shown that the degree of clumping also affects estimates of mass from modeling the light curves of SN Ib. 77 refs.
