Spectral analysis of SN 1987A : the first 7 months.
Abstract
Model calculations are presented for the photospheres of SN 1987A. The process of constructing the models is described and results are given from calculations of element abundances and colors. The mass of the hydrogen shell is determined using non-LTE treatment. Anomalies in the hydrogen line profiles in the optical and IR wavelength range are discussed in detail.
