Radioactive ionization of the envelope of SN 1987A
Description
The mechanisms responsible for the observed emission spectrum of SN 1987A during May-July 1987 are considered theoretically. Particular attention is given to the increasing strength of the 1.083-micron He I emission, tentatively attributed to ionization by gamma rays from Co-56 decay. It is suggested that the onset of gamma emission escape from the SN may coincide with the He I strengthening. 27 references
